I wouldn't take much notice of the nominal wattage, as others have said the Bafang G062 is rated 250w, 500w and 750w but it is essentially the same motor. I would just use that. No, for the same controller voltage and power , I don't think you will get any more power or torque than your...

On hilly rides my cadence sensored crank drive bike is significantly more economical than my torque sensored hub drive using exactly the same battery over the same route, taking approximately the same time. Not sure why, the hub drive is a 26" wheel with more "roadie" tyres - it does have...

@Az. do you know the max current setting for the 48v TSDZ8 from Woosh ?

Not sure the question you are asking, but am I correct in saying you have a Bafang G062 rear hub, 20" wheel, probably winding code 9 , nominally rated 250w and you are running it with a 36v battery. I think your existing motor will probably work fine with a 48v battery (the 21ah is just the...

Welcome Is it this one ? https://www.ebay.co.uk/itm/386974269338?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=-4xirrdcrge&sssrc=4429486&ssuid=e7wJGK-DRD6&var=&widget_ver=artemis&media=MORE I had a search in the forums here (best to do a Google search of this site rather than use the forum...

My question really was if I wanted a 48V nominal battery, capacity say 17Ah , with a max discharge rate of 30A, is there a noticeable weight difference depending on the type or brand of cells used

Is there any difference in capacity between the different cells ? I was wondering what the lightest possible battery would be for a given capacity - although I think the casing is a significant component of the weight

Wisper do a throttle option https://wisperbikes.com/full-throttle-option/ Woosh - as I understand it, you have to peddle initially to get the throttle to work https://wooshbikes.co.uk/?camino " If you don't want to pedal, use the thumb throttle (by simply pushing the throttle lever by your...

Welcome - although I did a mechanical engineering degree, and then went onto British Aerospace I got diverted into Computer Systems (and now counting down to retirement !)

that's interesting - I wondered if I could just ease off on the pedalling effort when I do a gear change it would reduce the power

I have just been doing a bit of off road and have realised that when you get to more technical bits, the Bafang BBS (on a Boardman 29er pro) has a bit of a disadvantage : if you are pedalling delicately a fine line on a slow section, then the cadence sensor kicks in and gives you a big dollop of...

Yes, I wondered if the older battery was not up to the higher power levels anymore and the new battery didn't have a high enough max continuous rating, there's quite a few that are only rated 20 amps max continuous discharge current

Can the batteries you are using supply the current ? 25 amps - what is their max continuous rating ?
