Introducing myself.

[Benton]

I am a retired power generation engineer, who still occasionally finds himself doing STEM
(science tech engg maths) business, albeit on a voluntary, informal or part-time basis.
My research background often takes me back to fundamental principles in most things I do,
while most other people would probably not bother with such an approach!

I came across Pedelecs purely by accident while surfing. I have been using electric bikes
since 2008. My main interest in joining is to keep my existing URBANMOVER UM55 Cruiser
on the road electrically, rather than using it as a pedal bicycle, which is what I have been
doing for the last few weeks. I may become a customer of another e-Bike in the future. My
dream e-bike is a Full Throttle, step-over or folding and rear motor one. However, I would
only buy it, if the battery could be renewed, or replaced, at a reasonable cost. Further,
detailed information including circuit diagrams of any pcd's and control units must be
available, and all essential spares that are prone to wear off in a few years must still be
available for at least ten years after purchase.

Why don't you convert your own from a suitable donor bike using generic parts that can be easily repaired or replaced ? For twist and go throttle (without pedalling) legally you have to get it approved at a DVLA testing site. Wisper do that as an option on their bikes
https://wisperbikes.com/product-category/throttle-electric-bikes/ but I don't there is anything stopping an individual from doing that

How about something like this as a donor bike :

Or there's plenty of potential donor bikes on Facebook marketplace / gumtree / eBay - I would say ideally get something with hydraulic disc brakes , or failing that mechanical disks and upgrade to hydraulic (cheap and easy to do)

Then add a kit eg from Woosh, (can get kits cheaper but very good customer service)

Woosh hub kits | Electric Bike Conversion Kits from Woosh

Woosh range of hub kits with choice of front or rear hub motors. Convert your bike into an electric bike.

Or crank drive

Tongsheng TSDZ2 and TSDZ8 CD kits | Chain Drive Electric Bike Kits from Woosh

The TSDZ2 CD kit: we have two models, with and without throttle.

Yosepower do cheaper kits and batteries :

There's also kits on eBay with KT controllers and displays (which have power based pedal assist levels rather than the inferior speed based pedal assist levels)

All ebikes work more or less the same, so you don't need circuit diagrams. On cheap bikes, like your Urban Mover most parts are generic and can be replaced or upgraded with similar items. The ones on your bike are pretty useless by today's standards.

Your 24v bike can be made into a really nice one if you upgrade to a 36v battery and a new controller. Unfortunately, the battery you have is rare these days, so best to gut the box and use it for storage, then fit a rack battery, or you might be able to find a suitable 36v cell-pack that'll fit inside the box. I've upgraded several 24v bikes like that and all the owners were very pleased with the results - more range, more control, more power and more speed.
