Search results for query: hub motor vs crank

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...

I'd be quite interested in the impressions of customers that try both crank and hub drive

I volunteer at a charity that refurbishes bicycles and recently rescued some bits from a stolen/recovered 20" wheel folder with a view to converting a previously rescued Dahon folder. Unfortunately because a lot of the wiring was inside the frame and had to be drawn out through small holes I...

I think lots of people buy e-bikes through the cycle to work scheme also use their bikes for leisure cycling. On one hand I think if you have got the money and if it brings you pleasure, go for it. On the other hand, if people are using it mostly for roads / light trails, I would advise them...

Traditionally, most bottom brackets were 68mm long with a 1.370" dia x 24 this thread. You'll find that on all catalogue type bikes and most bikes before about 10 years ago. Today, bikes have become more technical. MTBs have wider tyres and they want stiffer and stronger BBs, and road bikes have...

Hmmm.. just realized that I cannot simply edit my previous post one day after.. Let me see how I can put more info to make the SR Suntour battery solution wholesome. to provide a better context, SR Suntour HESC system appears differently under various brand names by region: UK and EU...

In case you didn't know, meters are used for checking electrical items. A crank-drive motor also works with electricity. It's a three-phase motor with hall sensors, electrically exactly the same as a hub-motor motor, but harder to test because the connectors are harder to get at. They also...

300 rpm at the crank, which is about 5 times the pedal speed of the average guy on this forum. If you tried to use it with normal pedalling at 20% of its max speed, the motor would run with very low efficiency and overheat. The Bafang BBSHD has a max crank speed of 120 rpm, which is much more...

Would 20A X 48V = 960W at the crank utilising appropriate gearing for a 20 stone rider be a good solution? I don't know if 20A is enabled by the alternative .hex file @Woosh has for his new 750W rated TSDZ8 motor, labelled and legally rated as 250W. And it's torque sensored, possibly not as...

Hi all, I am a new memeber here and completley new to any e bike build, i am very experianced in building cycles. I have recently stripped an E Mission trike that was giited to me as used but well cared for from an elderly friend. I know they indoor stored the battery, had no issues with it...

Not sure a Direct Drive hub is what you want for what you are describing - either a geared hub like the Woosh DWG22C (48v 17amp max power input) - (which is legal to use on UK roads) or maybe a BBS02B crank drive (48v 25amp max power input) (which isn't legal on UK roads) - can get with 20Ah...

It's because I've been dealing with electric bikes for 14 years, I'm a trained and certified Bosch technician and was an ebike mechanic in a shop for 2 1/2 years, so I learned to recognise the difference between an expensive crank-drive bike and a hub-motor.
