Danny MacAskill's Imaginate, Bicycle Stunts

Danny MacAskill has been up to his old bicycle tricks again. This time in "Danny MacAskill's Imaginate", a 7 minute video supposedly to give us a glimpse as to what goes on in his brain when he is thinking up bicycle stunts.

You can see some of his previous bicycle stunt videos here on The Bicycle Mechanic just by clicking stunts on the side bar.

If you have Netflix you can also watch the documentary about the making of Imaginate. (Although I will admit I skipped forward through some of the boring bits of the documentary. I just didn't have the patience to watch the whole thing.)

The stunt video is below!

Premium Rush - Bicycle Courier Movie

I just finished watching the 2012 bicycle courier film "Premium Rush" on Netflix. (And yes, I realize the film came out 2 years ago and I only now got around to watching it. Whatever. Sue me.)

Anyway I really enjoyed the film. Hence why I am sharing the trailer for the film on here.

So yeah, watch it on Netflix, buy the DVD, download it for free - it matters not to me. I just felt it was an enjoyable movie and wanted to share it with my fellow cyclists who may not have heard of it.

I also find it interesting that the film didn't pull any punches when it came to crazy cyclists, stupid car drivers, and idiot pedestrians. (And don't forget the police, who are often corrupt or clueless.) They all got slammed. Proof positive that drivers, cyclists and even pedestrians are equally stupid when it comes safety issues.

Demystify Your Bicycle at HUB (Vancouver)

HUB in Vancouver B.C. is offering a series of small 3-hour long introductory classes to teach people how to fix and maintain their bicycles. The classes are held at The Pedal Depot (1830 Ontario Street) in Vancouver.

More information on this topic is available at

The introductory classes only cover brakes, gears, hubs and wheels and cost $200 to sign up for all 4 classes.

The graphic below lists the classes as "intermediate", but the classes really are designed for complete beginners.

The "beginner" 2-hour class is more of a "complete basics" class which covers jargon, terminology, etc and almost no mechanical skills and is designed to teach people how their bicycle works, and what the different parts are called. The beginner 2-hour class does a basic inspection, how to clean and oil a chain, check for wear and tear, and patch a flat - basically all things you could learn from a YouTube video or by reading The Bicycle Mechanic.

So if you already know how to fix a flat, you probably don't need to take that course.

On the other hand if you are looking to become a true professional bicycle mechanic, you are probably best off taking the six week bicycle mechanic training course at Quadra Island (which is not far from Vancouver), which costs $2500 for tuition and residence. Students come from all over the world to take the course at Quadra Island because it is the most intensive and comprehensive bicycle mechanic training course in the world.

An Essay on the Topic of Abandoned Bicycles

Many people in Toronto (and other cities like Toronto) have bicycles.

But many people also either apparently lack the mechanical skills to fix their bicycle;

Or they have skills but are simply lazy.

I am uncertain which it is.

What I do know is that I see a lot of abandoned and "broken" bicycles on the streets of Toronto on a regular basis.

Sometimes I even take the abandoned bicycle, I fix it up and I sell it. It isn't thievery. It is an unlocked bicycle with something broken on it.

Often it just needs a replacement part and the part is somewhere in the $5 to $50 range, but for whatever reason the previous owner was too busy or lazy to go to a store, buy the part, replace the broken part, bob's your uncle, your bicycle is (practically) good as new.

And it boggles my mind that the people abandoning their bicycles don't know they can do this. Something breaks, they are too lazy to fix it, so they just abandon the bicycle because they think it is easier to go and buy a brand new bicycle instead.

Let us assume the average person spends at least $200 on a new bicycle. If they make $20 / hour doing whatever it is they do, they just spent 10 hours working just so they could get a new bicycle.

When they could have just walked to a store, purchased a $5 to $50 part, replaced the part, and the comparative cost to them would have been either 15 minutes worth of work or 2.5 hours worth of work (assuming they are getting paid $20 per hour).

And now hopefully you understand why my mind is boggled by the people who just abandon their bicycles and go buy new ones, and understand why I am writing this essay / rant. Essay writing is a great way to get your point across.

It is almost as if people either don't realize how cheap it is to fix a bicycle, or they don't realize how easy it is. 90% of repairs are actually so easy a 12 year old could do it.

It is the 10% of repairs that take a bit more brain power.

Take for example any bicycle which is tossed out because it has a flat tire. (I have lost track of how many bicycles I have seen abandoned just because it had a flat tire.)

You either patch the tire with a patch kit and glue;

Or you buy a new tire that is the same size.

Presta, you're done! (And yes, that was valve pun.)

Next, lets take the example of any bicycle that was abandoned because the chain was tangled up / snagged on something / broken / etc. (This is another very common cause of abandoned bicycles)

Just rip the old chain off, buy a new chain the same size, buy a chain tool, install the new chain using the chain tool.

Bob Schrader's your uncle, it is done!

Sometimes I have found abandoned bicycles that the only thing that is wrong with is that the brakes don't work.

In which case, just follow the instructions on The Bicycle Mechanic for fixing the brakes (seriously, they're not that hard to fix), and voila c'est fini!

In some cases they might require you to purchase new brake pads. They cost about $5.

And there you go, three of the most common reasons why people throw out / abandon their old bicycles - and how easy it is to fix those three common mechanical problems.

Now I could understand if someone was throwing out a bicycle because they were leaving the country and could not take the bicycle with them.

In which case the thing to do is take it outside, put a piece of paper on it that says FREE BIKE, and watch how quickly it disappears. In which case the bicycle should be in perfect working order.

Typically you will see the perfectly working free bicycles outside of apartment buildings on the 1st of each month. The previous owner moved out on the 30th or 31st and left their bicycle outside on purpose for someone to take it.

That I can understand. But for the silly people who abandon their bicycles because it has a broken part that could be replaced for $5 and some brief elbow grease? Those people need to realize how easy it is to fix their bicycle.

Schrader Vs Presta Valves

If you read my post about Bicycle Mechanics in Leaside Toronto then you know I purchased two things today: #1. A Presta-Schrader valve adapter, and #2. a bicycle pump that is compatible with both Schrader and Presta valves.

I already have a Schrader bicycle pump, which is pretty standard. But I didn't have a working Presta one so I decided to get a new one (that works) and in the event it ever breaks and I need an adapter, I therefore bought an adapter too. I call it the Mechanic's Rule of Tool Redundancy - when in doubt, get two or more in case you cannot find the other tool, it breaks, or cannot be used for whatever reason. This is why you can never have too many toolboxes, screwdrivers or tools in general.

Since the invention of the pneumatic tire many valve types have come along but for bicycles the two most popular that are still in use are Presta and Schrader (or as I like to call them, de French one and zee German one - not because that is their country of origin, just because they sound like they are French and German).

The Presta valve is the skinny one of the two and is slightly more cumbersome to use, having a lock nut instead of a spring to make sure it is closed and doesn`t leak air. The Presta valve is more popular on racing bicycles because it is skinnier and doesn`t leak air easily.

The Presta valve also enabled racers to inflate tires with a simple pump with attached chuck (pump head) and no hose. Having no valve spring to overcome it is therefore faster and easier to pump gas into the tires. If Schrader valves had a valve depressor it could speed up the process, but it would make the pump head larger, heavier and impractical.

Because of the small diameter of the Presta valve it requires a smaller hole in the rim, which means that the bicycle rims can be narrower. This saves on weight and increases overall speed.

However Presta valves break easier, are harder to fix, are not widely used except in racing bikes, and Presta pumps break easier too (based on my first hand experience with them). Some Presta valves have been made with removable cores to make them easier to fix, but demand is so small that they are uncommon. Removable Presta cores can be identified by two wrench flats on the coarse valve cap threads.

In contrast Schrader valves are robust, universally used, and have an easily removable core. And they are easier to fix. Spring closure makes them simpler to use because one needs only to press the inflation chuck onto them at any gas station that has an air pump. With foot or hand pumps, a screwed or lever chuck provides the valve depressor - and it can tell you what the pressure is in the tire too.

My advice for my fellow bicycle mechanics? Get a Schrader pump and a Presta adapter. You might never use the Presta adapter, but at least you will have it when you need it.

Bicycle Mechanics in Leaside Toronto

Sandy's Bikes and Books

Address: 95 Research Rd #1, Leaside, Toronto, ON M4G 2G8
Phone: 416-467-1035

As you can see above Sandy's Bikes and Books is just that, a bicycle mechanic / bicycle store that also doubles as a book store. Oh and vinyl too. Don't forget vinyl.

Sandy himself is very nice, very talkative and I am sure I will be going back there again to buy bicycle parts. Today I purchased a Presta-Shrader nozzle adapter there for a mere $3.04 (tax included).

GEARS Bike Shop in Leaside

Address: 109 Vanderhoof Ave, Leaside, Toronto, ON M4G 2H7
Phone: 1-888-984-3277

GEARS is all about racing bicycles - and I make this review with the knowledge that GEARS has been sponsoring this blog for the last 2 years and hopefully will continue to sponsor the Bicycle Mechanic. So, knowing that these are high end racing bicycles expect that if you want to purchase a bicycle at GEARS that you will be spending a pretty penny. However at the same time I will point out that their service was excellent when I said I was looking for a Presta pump. What I got was an Evo Hurricane pump which is compatible with both Shrader and Presta valves. Cost was $29.99 + HST.

Enduro Sport in Leaside

I am not going to list Enduro Sport's address or phone number here.

Why? Because they snubbed me. I think they saw my GEARS bag and then chose to snub me. Didn't even ask if I wanted help, if I was looking for anything, etc. So I am snubbing them back in return. Nyah nyah!

Seriously though, I have been to Enduro Sport twice before and they were rude both times. This is the third strike / last straw in my opinion. I have given them three chances to redeem themselves and they were rude twice and snubbed me once. I doubt they remember me from the previous times I went there. Both times was in 2009 when I first started this website. So having been treated poorly three times I shall now return the favour.

Call it the Golden Rule of Shopping - If you are rude to the customer with the gold, they take their business elsewhere. And the customer is always right.

Men's Cycle Fashion could use a little more High Fashion

As I have made clear in previous posts I am not a big fan of some of the cycling gloves or cycling helmets that are sold in stores. So I apologize if I rant about cycling fashion for a bit.

They're not very manly and I wouldn't get caught dead wearing some of the outrageous form fitting clothing that are often sold in cycling stores.

Just because Lance Armstrong wears it doesn't mean you should. There are lots of things Lance Armstrong does that you should NOT do.

Are you a professional cyclist who races for a living?


Then stopping wearing those ridiculous clothes.

Sorry if I go all fashion police, but I firmly believe that men can dress much more sensibly when on a bicycle.

Let us say for example that you are meeting someone for a date. Possibly even at a fancy restaurant. And if you are a true Toronto cyclist then you will probably bicycle there because you don't own a car.

Now when you show up at Ritz Hypothetical your date is not going to be very impressed if you show up all sweaty and wearing tight fitting latex.

But she might respond quite well to your handsome appearance if you showed up looking like one of these guys from Kish Wear - Men's High Fashion:

It is basically following the same golden fashion formula all cyclists do...

The Cyclist Golden Fashion Formula - Wear form fitting clothing that is fairly tight to the body. Nothing baggy that might get caught in spokes or gears.

That means you can wear dress shoes and socks.

It also means you can wear tight fitting pants, like the pants below also from Kish Wear. Or the sweater, again, same place. This means you don't have to look like a sweaty cyclist and can show up looking posh and suave for your date. First impressions matter.

Next let us pretend for a moment that you are going to a job interview instead of a date. Assuming this is an office job you probably don't want to show up for the job interview looking like a sweaty cyclist who doesn't know how to dress properly.

But you would probably score points if you showed up dressed like this:

"Oh but I am an individual and a non-conformist. Why should I have to wear an uniform to get a job?"

Seriously. What world are you living in?

If I was the HR rep you are meeting and you show up in either:

A. Cycling gear covered in sweat.

B. Dirty jeans and a ripped t-shirt.

Then I guarantee that unless your job is to be a cyclist fashion model or a construction worker, then you are not getting the job.

So if you're hoping to get a job in an office then you better get with the program and wear the uniform. And to be fair, all clothing is uniforms. It is just different kinds of uniforms.

If I taking my girlfriend to the ballet - eg. The Ballet Creole, which I love - then I will be dressing accordingly. Washed, freshly shaved and wearing nice shoes too.

Same goes if I were to go to a classical music concert. Or any event where it is expected that people dress accordingly.

And truth be told, I admit, I probably would not take my bicycle there because I live in uptown Toronto now and it is rather a trek to either of those locations via bicycle. So we would probably take the TTC or drive instead. (Sue me.)

If it something super important, like a wedding or a funeral, I might even wash the car first.

What I am definitely not going to do is show up at a funeral wearing cycling clothes, sweaty, and then bicycle from the funeral home to the cemetery.

Not such a big deal to go to the cemetery when you are just cycling through and enjoying the purty trees et al. But not such a good idea when you are actually there for a funeral.

I think part of the problem with some cyclists - the ones who wear cycling clothes a LOT, like on their way to work, on their days off, on dates, etc - is that they really have no life outside of cycling, that they are essentially cycling snobs, and that they are also clueless of how ridiculous they look.

And I am not just talking about the ridiculous helmets cyclists sometimes wear.

Nor am I talking about the idiots who buy professional cycling team jersey kits. You know, the ones with matching socks, shorts and jerseys that look completely idiotic when you wear them. Especially if you have belly flab sticking out the bottom of your too tight shirt. Buy clothing that fits and actually looks good. Looking ridiculous only makes you look like a moron.

Nor I am talking about the guys who wear baggy pants and then get "rookie" grease stain marks on their pants from where the chain and gears are rubbing against your calves. That is clearly a case wherein people need to learn how to wipe down their bike regularly and learn how to dress themselves properly for cycling.

Now I am talking about the idiots who wear hydration packs on their backs because they are too lazy to get a water bottle installed and then use it accordingly. Oh look. Its a camel back. Are you riding a mountain bike in rough terrain far away from the convenience of Starbucks? No? Then taking that stupid thing off your back.

What I am talking about is all these things and much more. The people out there who apparently have no fashion sense, wear ridiculous things that they don't actually need, and then apparently think that everyone else is an idiot for not wearing a special helmet, jerseys, hydration packs and everything else that you THINK you actually need.

The truth is you don't need any of it.

What you do need is your bicycle, some shoes and socks that fit, some shorts that fit, possibly some cycling gloves, and that is it. (And for female modesty, maybe a sports bra and a shirt.)

And if you are going somewhere special then you should dress appropriately for your DESTINATION.

Dress for your destination and dress stylishly when appropriate. Dressing like a loser / cyclist snob isn't going to score points with anyone else.

Brazil Prison Bicycles

Apparently there is a prison in Brazil that allows inmates to bicycle and produce electricity, which in turn is tracked and reduces their sentences.

Presumably this program is only offered to inmates who commit minor crimes (like theft, etc) as opposed to the more violent criminals.

I would be curious to learn how much electricity is actually produced this way.

It might be, for example, more financially viable to have the inmates build windmills instead and those windmills be used for producing electricity. Longer term results as opposed to short term gain.

Not dissing bicycles or anything, just saying windmills seems like the smarter solution if their end goal is electricity.

How to Fix a Sturmey-Archer 3-Speed Internal Gear Hub

Hi Charles,

I have an older model Raleigh Sports with a Sturmey-Archer internal gear hub that I've been having troubles with and was hoping to get repaired.

I've taken the bike to a couple of different repair shops already and it has always been returned with the same troubles.

I stumbled across your site when I was searching online for Toronto-area bike mechanics that appear to have experience with 3-speed internal gear hubs.

Would you be able to take a look at it? If so, what's the process and where should I bring it.

Your assistance would be greatly appreciated.

Steven S.

Hello Steven!

My advice:

Buy a new internal gear hub, possibly from a different company.

Internal gear hubs are basically supposed to require a little bit of oil once or twice per year for maintenance and that is it. If it broken however, your best options are to return it to the manufacturer for a replacement (if it is still on warranty) or if the warranty is up, buy a new one.

What has most likely happened - in the event it is broken - is that one or more pieces inside the gear hub have SNAPPED IN HALF or into several pieces, and then the smaller pieces have jammed up inside the internal mechanisms, possibly doing other permanent damage. The internal pieces are not designed to break, but with age, wear and tear, metal gets fatigued and can eventually just snap.

It is possible that a piece inside has just come loose, or bent, and it just needs to be bent back into shape or placed back in its proper location. Now there are some experts out there who know how to repair internal gear hubs - but it is pretty rare knowledge. A bit like finding a clockmaker who knows how to fix pocket watches. Not many people go into that sort of thing as a career these days.

Thus it might save you a lot of time and effort just to buy a new one.
Now you might wonder why I suggested possibly buying a new internal gear hub from a different company. I am not dissing Sturmey-Archer's quality, I am sure the quality of their internal gear hubs are just fine. But feel free to shop around anyway and browse your options. No doubt the higher quality gear hubs will be more expensive, and the lower quality ones cheaper. You get what you pay for. So if you find an internal gear hub from Sturmey-Archer that you like, that is in the right price range, absolutely, go ahead and buy it. However if you find one you like from a different company which is higher quality - and possibly has a lifetime warranty, you might want to buy that one instead.

Here is a YouTube video about fixing a Shimano 3-Speed Internal Gear Hub which might help you a bit if you decide to try and fix your gear hub yourself.

And here is another video about Sturmey-Archer three speed gear hubs and how they work, and should give you insights on how to fix yours depending on what is broken on the inside. Between this video and the one above you might be able to fix yours.

Happy Repairing / Shopping!

How to make a bow out of a bicycle wheel

While it is an amusing design for how to make a bow to practice archery with, I do NOT actually recommend the bow designs shown below.

My reasoning is fairly simple. I have been doing archery since 1989. I have over 12 bows myself, and two things I have learned over the years are the following...

#1. Decurve bows do not make good bows. (The designs shown below are definitely decurve.)

#2. The bow below isn't really a bow. It is really more a kind of complicated looking slingshot using a giant rubber band.

The end result is a slingshot that really is not a bow, doesn't really work that well, and would ultimately be a waste of time for anyone who is not into slingshots.

So if you are into slingshots, go ahead and use the designs below. If you are into archery I have suggestions to make at the bottom for how a person could make a proper bow - in this case a recurve bow - using bicycles parts.


You will need...

Old Bicycle Wheel
Giant catapult rubber band - $5. (You could use a rubber inner tube, but it isn't as powerful.)
Saw to cut the bike rim
Drill and drill bits.
Scissors / Tin Snips or some way to remove the spokes from the wheel
Metal file to tidy up the cuts
Pliers for bending
Eyelets + Retainers for the eyelets (plasterboard expanding grommets work well)

The design above is pretty much self explanatory just by looking at the photo. It is basically just a frame for holding rubber band for the slingshot. The bicycle wheel does bend a bit like a bow, but it is the rubber band that does 90% of the work.

Cut the wheel, smooth down the rough edges, drill some holes in it, add the eyelets, etc, attach the rubber band and you're done.


#1. Cut the wheel into quarters instead of halves.

#2. Line the quarters up like below


#3. Weld them together to make the classic recurve bow shape.

#4. Drill holes in the top of the bow and the bottom of the bow, roughly one inch from the ends.

#5. Using bicycle cable, string the bow between the two holes.

#6. Find a sturdy way to affix the bicycle cable to the bow. I recommend drilling the holes big enough to fit a bolt through there, wrap the cable around the bolts a bit, slide the bolt through the hole, tighten with a nut on the opposite side and make it super tight so the cable won't come loose. Repeat process both ends of the bow.

#7. Wrap bicycle handlewraps around the handle where you will be gripping the bow.

#8. Optional - Make an arrow rest using random parts from a scrap bicycle.

#9. Optional - Make stabilizer using random parts.

#8. Use a crimp to add a bead on your bowstring so your arrows don't slide up and down.

#9. Practice with your new recurve bow!

#10. Send me photos of the finished product so I can show others what you did!

Gas Engine Bicycles - For lazy gasoline lovers?

I am not going to pass judgement and not talk about gasoline bicycles, but I am going to say that many cyclists see gasoline powered bicycles - and sometimes even electric bicycles or e-bikes - as a betrayal of what bicycles are supposed to be: clean and efficient means of transportation.

The video further below is an example of one such gasoline powered bicycle or g-bike.

Whether you like g-bikes, or despise them, the video is an interesting example of one way to tinker with bicycles and try something new with them.

After all, this wouldn't be a bicycle mechanic blog if I didn't showcase examples of people tinkering with their bicycles and trying something different.
