Hi,
For those that might remember, I started the below thread just before the first 2020 lockdown. hence nothing much has happened since.
www.pedelecs.co.uk
A brief summary is that I purchased two Trek Hybrids from Cytronex in Winchester in 2008, the batteries are now both defunct. At the end of the last thread I had decided to go with another hub motor kit, that of course never happened.
Having started the whole decision making process again now, I have decided on fitting the above to my Trek due to my weight which is now over 19 Stones (hence the need to cycle more)( I am aware of the legalities surrounding this choice) and then if all goes well fitting the same but lower powered kit to my wifes Trek as she is about half my weight.
Having watched numerous videos and waded through mountains of jargon, I am still confused by a few things that hopefully someone here can answer for me. I will be starting from scratch as a complete novice buying a stand, tools etc. Hopefully learning a lot along the way.
Similar kits are on Amazon and AliExpress but with different choices to be made. I would prefer to go with Amazon in case of any problems, although AIiexpress can deliver a few weeks quicker.
Save me waffling on I will just ask the questions if that's OK and am sure more will come from the answers.
1. The motors are advertised as 48v 750W, does this mean I should stick with 48v battery or would a 52v be OK?
2. The dropdown list on Amazon lists a mountain of battery options, some mention 44T 48T etc and 17.5Wh etc, some including 48 or 52V as well. The Aliexpress kit appears to offer a few battery choices and it says just 44T. So it appears that Amazon has a lot more options but I have no idea which is a good or bad combinatiion?
3. The bottom bracket seems to cause some issues on some videos and I have no idea how to find out what mine is without stripping it down first and taking a chance the motor fits easily. Are there any easy ways to check beforehand?
Thanks
Steve

Think a kit is the cost effective option, but at 18St 8Lbs, I may be wrong.
Hi, The background is that I purchased two electric cycles from Cytronex in Winchester 12 years ago. They were mainly for taking on our Motorhome. They are Trek Hybrids, you press the button and the motor kicks in and braking shuts it off, front hub motor, bottle battery. Although very lightly...
