Re: High power ebike means none of the rules apply to me

Those who write the laws in the hope to save 2 pedestrians a year from stupid bike riders, are the same who are giving the industry licence to kill with chemicals, poisons and pollution... when they are not just sending your kids to war. 99.9% of riders will never hurt anyone but themselves in their...

Re: Reliability - Are there numbers?

This is about how and where you ride. If you are commuting everyday, doing lots of mileage in all conditions, a big DD hub is a sure value. I’ve had 2 Cromotors. One did 25000 miles before I shorted it because I postponed too long replacing the bearings. The other one had a bearing replacement at 20...

Re: Hub motor locks when given throttle

If you just changed the phase wires, either you have a short or you mixed up the connecting order (phases or halls).

Since a short does usually fry the controller, I’d look for the phase and hall combo first.

Re: Ken Blocks Bicycles

I own a Fatboy Chopper, that I postponed building for a decade. It sure wouldn’t be on my list. It is an interesting bike, but not my riding style. Choppers aren't primarily for riding. They're costumes that you can ride if you want to. A chopper is a highway ride, made for long distance comfort. E...

Re: Ken Blocks Bicycles

MTB are not easy to build, but they are making the best ebikes for sport riders. When choice of frame is about batteries, it is to build range at the cost of performance compromise.

You’d have better luck in Taïwan. There is a Ti cargo bike on the market already, British I believe and pretty expansive. Any good Ti bike frame cost a lot.

Re: Why not comfort bikes?

The reason for a recumbent bike is efficiency. I can see riding a tadpole trike for comfort, but on 2 wheels the recumbent posture does affect handling a lot. Handling delays are not making a comfortable ride, psychologically. I mean, unless you are on a long free road. Navigating in city trafic on ...

Re: Why not comfort bikes?

With speed the aero drag curve steepens, forcing lower design. Speed tracks are also very smooth. Rough riding a bike, it is better on large wheels and long suspension travel. That is why dirt bikes are so different from road bikes. Road bikes are all about performance and stability. Yet, race them ...

Re: Fast Ebike for a tough commute

Come-on. I am going downhill 9 grade 80 mph with a 4t DD hub. I climb avg 9 grade at 50 mph for miles.

A fast commuter is best built with a big DD hub and RC lipo. Otherwise it will be heavier, more expansive, more maintenance.

Re: Why not comfort bikes?

Yep. Comfort has many conditions. Speed and terrain of course, does affect the need for suspension. Yet, I believe most of us are riding faster average with an ebike than a bicycle. When it comes to choose what to ride, some have a cyclist view, some others a motorcyclist view. All of those who are ...

Re: Why not comfort bikes?

Comfort has many conditions, and the most important is suspension. It is much easier to adjust the geometry of a FS frame, than adding suspension to a frame with the geometry that you like. That is a good reason already, to build a street bike on a downhill frame. But it is not the only one. DH bike...

Re: 138mm in 135mm Aluminum dropout?

You know that your alu frame is good to spread, when it does return to its original width after the wheel is removed. If it does, it will last without any damage. Yet, spreading a frame dropouts does make a slight angle in disc brake fitting, that might need to be corrected with a spacer between the...

Re: Could I get an opinion on this freewheel issue?

Nope. You need big 10 mm washers (The axle flat is 10mm) to shape an axle shoulder spacer. Then you file them 10mm holes each side to 16mm to match the axle. There is no need for any fancy tools and workplace, just a chainsaw file or any other round/half-round file smaller than 10mm.

Making a spacer for the axle shoulder is easy. If this simple task is too much for you, maybe you deserve to ride the cheap Chinese freewheel. :roll:

The good side of having two white wires, is that you don’t have to guess cutting the white or the red. :mrgreen:

I have built Canmore. Well, part of it. I had a framing contract for the olympic village. There were no courthouse then, not even paved streets. But there was a scumbag robber already. I believe he was behind this idea of building Canmore in the first place.

When I built my first, I said we should have ten years before the police start enforcing ebike laws. I was wrong. They still enforce traffic laws, thus powerful ebikes are treated exactly the same as legal ebikes. I find it is a good thing. Rule the behavior, not the power. Here this guy would have ...

Yes it can be done, but not as simple as you think. You will need a power supply that is running from the cars charging stations, with a voltage and Amp output that suits your battery.
