You use the DT Swiss chart just like you would the Sheldon Brown one. The axes are not reversed but they are swapped. You pick your rim inner width, which is easy to learn via typical rim specs, or take a measurement off a pair of calipers. DT shows you an illustration (measurement B) of what...

Thats pretty much what I do, but that literally puts me on Cannery Row in Monterey CA, which is packed with tourists both on foot and in cars. The vehicles are going 15-20 mph and the drivers are rubbernecking themselves, so speed is good but you still have clueless bozos to avoid. Boo Hoo...

A key to tidy wiring is to find a place to hide the excess. Wiring is nowhere near as noticeable if its snug against the frame, or bundled to for example the brake or shifter wires. The problem is not the use of color coded zip ties or split loom casings. Its the 'coiled and crammed' part...

The DT Swiss tire width chart I llinked above shows what the Sheldon Brown chart does, plus it goes up to fat bike widths. Its a much better chart to use as an example. WTB also has one that is a little more conservative.

This fix is not a fix, by any means. Not going to survive for long and of course its already not working right as noted. The mission statement on my web site reads DIY does not have to mean half-assed And this is definitely half-assed. Not a kind thing to say but really... this is a Darwin...

Oddly enough it solved the problem here. A 12 mph speed limit was enacted for a crowded segment of the tourist-laden bike path. It was enforced for a short time, and enforcement was subsequently abandoned. In the years since ebike use has exploded to the point where they outnumber bicycles by...

Cali Ebike is a solid operation but I believe it is also run by a single individual now. I have bought from them repeatedly over many years, most recently a Lekkie 28T chainring I got in a few days just about a month ago. I would try again via email. They usually respond in a day or so. A...

One more sign that ebikes are marching towards ubiquity, and the idea of a bicycle you have to pedal is becoming a thing of the past. Especially for a younger generation who sees them as basic transportation rather than some sort of exercise device where if effort is not demanded, it loses its...

Yes anyone can get access, but its not complete access unless you are a dealer. Or at least thats how its been since it was released. We'll see what happens to you.

I can get a different minimum number if I re-grease the hub (goes down), or I clamp it back together a little wrong. If I do a re-grease and the minimum jumps to 60w then I know I've done something wrong and have to go back over it again. Thats actually happened to me.

That sounds like it would solve one of the major negatives with regard to using regen on a DD hub system: You can never just coast and take advantage of the momentum you have earned on a regen-enabled DD system. Like you would if you are riding in town and you can see a light turn red a half...

I have done the wider H bar on several bikes with great success. I went to them due to a wrist injury (hit by a car) and the 45-degree angle of the bars gave a natural wrist bend that was the difference between being able to ride a bike versus riding the couch instead. Here's a fairly mundane...

You have already figured this out, but I will echo the concern @jabberwocky voiced, from direct experience. <intermission> I built a chromoly-framed 2wd bike that has twin geared-hub Bafang G060 motors (rated for 80 Nm each) and mated them to twin 35a controllers and a 52v battery that has a...

Cleaning the discs will un-bed the rotors. Actually the worst thing for getting rid of most forms of brake squeal. Disc brake rotors have an invisible coating of brake pad material on them. This coating silences the brakes when in use. If you lose this coating, the brakes tend to squeal like...

Yeah but all the hand-wringing over throttling pretty much only happens on ebike forums. The demand to pedal the bike Is not a real-world concern shared by the general public. Being all over this ebike forum world, we forget we are only a small bit of a much larger world. Big fish, small...

Generally if you spread the dropouts like you describe the frame is dead. The only solution is to braze in new ones and the cost of having a pro do that is often enough to call it off. The vast majority of ebike frames are not at the quality level of a proper analog bike that can be worked on...

The requirements of the step-thru place quite a limit on the choice of bike. I have to say the Frey C-C is the only step thru that, over the years, I have considered acceptable for that style of frame. Its got good suspension components, a motor that is being run well below its hot rod level...

Here where I live, the city council rsponded to all the usual complaints by implementing a 12 mph speed limit on the main trail here - which is a 'recreation trail' but its the main artery for cyclists as transportation since the streets are narrow and crowded, with no shoulders oftentimes...

That still doesn't cover the home builder. It DOES cover against a manufactured ebike that had a class sticker in the first place, where the DIY person is modifying an already-finished product. But if you build the bike yourself as a conversion from an analog donor, it doesn't apply. You...

Does the G062 have the 'bigfoot' internals the G060.750 used to have? Bafang slimmed the 750 down to match the other lower-rated versions of that motor but I'm wondering if the 1kw version got to keep the bigger, more better internals. If you aren't sure what I am going on about, I tee'd this...
