the Pas sensors with the hall sensor anchored to a metal ring is intended to sit on the chain ring side of the crank and is expected to be held in place with the bottom bracket retaining thing.. if you want a left side sensor lift the one pictured or buy a similar left side sensor. dont get...

My 2 bob's worth. I was new to all bikes not having been on one for over 50 years after giving up on my beloved Yammy due to constant nagging by the lovely Jane. I knew nothing of the terminology and hadn't a clue what a bottom bracket was, let alone a crank. This forum has been helpful to...

@Nealh's TSDZ2 would be better for that, high pedal Q factor, and his motor will fill with water faster. That looks just the thing to mix remaining fragments of bike thief bodies I'm disolving in giant vats of acid - it's easier to flush away and impossible to identify scum, when blended into...

Your crank motor would be handy for my fishing boat. It needs an anchor to keep it still while I'm trolling. It's the battery I'mreally after for the trolling motor. It's really useful for when I do the forum on my boat.I can troll much quicker with electric assist...

I don't hate them. I'm building a bike now with one for myself. There's a place for them. It's a case of weighing up advantages against disadvantages according to your specific circumstances and needs. For an average guy wanting to ride around on the road, the disadvantages always outweigh the...

How many times have you heard of any problems with heat on this forum. It’s very unusual to get motor heat problems, though controllers can blow mosfets if they over-heat. That happens with both hub-motors and crank motors. The controller's in crank motors can't get rid of the heat because...

Guess you'd have to try one, but you probably never will - the big advantage is ease of pedalling while dragging heavy weight, without needing an expensive battery capable of discharging high continuous current. I don't know how much you played with the firmware parameters when you had the...

I can't see any sense of using a crank motor on a bike with 20" wheels or smaller. You only get the disadvantages.

Isn't it step-through frames that mask the weight saving of small wheels? You mostly see them in step-through folding bikes or overbuilt BMXs. Given that there doesn't seem much alternative to step-through, the main benefit of small wheels here is in bringing a hub motor's climbing ability...

Doesn't her fazua have a rear hub kit?# edit: you are right, it has a crank drive motor and a hub gear.

Fairs, appreciate the advise

It's an urban myths that hub motors don't climb hills as well as crank drives. If you run with 48v, a hub-motor can tackle any normal hill with ease. You get 30% extra torque compared with 36v.

Actually, I did think about that, but the shop was more or less in sight and I had a pocket full of money. If that guy wouldn't have accepted the job, I would have found another solution. I should really go back and see what they sell. I was in such a hurry and panic that I didn't have much of...

Good point. That's 26" wheels, so 38T would be a comfortable minimum for 29" . What I'm saying is that it would probably be better to get a cheap used catalogue bike with disc brakes to convert. Unless there's something special about you and your rides, it'll work fine with any cheap conversion...

What is it about these TSDZ2s? Not only do owners have to contend with screw anxiety, shaft snap anxiety, moisture ingress, pedal high-q factor, overheat and melty blue gear anxieties (among others), now they've got crank anxiety... An aluminium crank arm has never fallen off my Bafang BBS01B...

On enforcement of regulations. What enforcement? As in many other spheres of public life, the enforcement of e-bike power regulations, and e-scooter rules is an incredibly rare event - so rare as to be laughable. It is a waste of time to even trouble oneself about coming to the best definition...

i think still a lot of people don't understand how motors work. 200w would be enough power, but a motor's power varies between zero and 80% of its input power, depending mainly on its speed. If a motor could max out at 200w, it would slow down when it encountered a hill. As it gets slower and...

I would suggest review of your system parameters. It is clearly not up to the job. Reasonable increase of Amps should help. If not, then maybe change of a motor and battery. Ask Guerney. He should know how to squeeze more omph from Bafang motor.

Increase the Bafang controller's amp limit and set "Keep current" to 100%? No hill has done that to me and my BBS01B. https://edrivenet.com/bafang-programming/

Really? Raleigh moped at the beginning of the 1960s had power outputs of 1.3bhp to 1.7bhp. That translates to 969 watts and 1267 watts, not 500. These were VERY conservatively powered machines and modern 'moped' class bikes are limited too 2.5bhp or 1864 watts. I was amazed at some of the...
