So if I buy a 48v 17ah battery to fit on the downtube,there all going to be the same physical size?

Its the physical size of the battery that matters

I'm just looking at sellers battery measurements and wondered if there was a brand or seller that were known for physically smaller ones.

Your first impression is correct,and I've seen it done,was just thinking smallest possible to make it easier.ah well....back to the drawing board.

Does anyone know what the smallest in frame battery is? As in physical size.its for a full suspension frame with the rear shock upright next to the seat post.

Thanks for the replies.lots to learn and get my head around.

I have seen some deals on ali express,good reviews,with a 3 day delivery time from within the UK. Be good if I could find a supplier in the Manchester/Liverpool area,but I'm not finding any. On another note, the company that modified my car for me have also done bikes for disabled ppl.might be worth a chat with them.

Thanks for that info Tony so a mid drive bafang with 48v battery and a throttle.what difference does the motor wattage make? Looks like woosh don't have any motors until February.

Thanks for the replies. To answer some questions I'm 14stone.not fit at all...probably an 8 or 9 .I want a mid drive motor ideally,and I want to ride a mix of tarmac and dirt,with lots of towpaths.a range of 30-40 ,miles would be good. I saw a set up on youtube.bafang hd 750w with a 48v battery and a egg display i think.my short term memory is not good.

Hi klarisa, I'm good today thanks.

I know nothing about ebike kits. Im looking to convert my 2008 trek fuel 8.ive been looking at bafang motors,but there's so much choice.i have M.S. and suffer from fatigue in my right limbs especially. The only thing I know I really need is a thumb throttle I can use with my left hand,and the ability to use throttle only to get me going. What difference does a bigger watt motor make? And do diffrent volt batterys work better with diffrent watt motors? Sorry if this is confusing.

Just joined,hoping to get electrified in a nice way soon.a bit about me. Life long cyclist,bmx,road and mtb.miles have been almost non existent for the last few years due to M.S. one aspect is fatigue,I'm looking to buy a bafang kit to get me back on 2 wheels.bests a mobility scooter right? I suffer from brain fog as well,so struggle to take in lots of information at times.anyway,I've questions to ask in another part of the forum.thanks for having me. Yours,William of wigan.:-)
