Byocycle model identification

[Millymoobag]

Hi all,
I have been given this Byocycle back after a decade.
It's dead but before I look at it I would like to know the model so I can hunt down information on it.
It's the model they bought out with the Nu Vinci auto gears if that's the way it's spelt.
It died about 10 year ago and the battery was wedi benni (dead).
The owner never bothered till recently when it went to wherever and he said that something's not compatible but doesn't know what and a couple of batteries were tried, how I am not sure as the battery was locked in the rack still and they didn't have the key. But whatever maybe there's a way without removing the old battery
Any info appreciated .

Thank you very much Peter.

looks like a front hub drive which has been installed upside down?? And it looks like the controller is housed in the battery mount rear? so without the keys may require destructive persuasion to reveal its secrets.

the motor position (upside down) would indicate the risk of water ingress and motor issues tho..

Seatpost looks bent with saddle pointing upwards. You might like to make sure it is safe to ride.

A lot of hub bikes leave the factory with the motor cable exiting from the top.
In a lot of cases the wiring doesn't allow an owner to rotate the hub to prevent water ingress so the best solution is to use a pliable rubberised sealant to waterproof the entry /exit.

A woman at work has 24v small wheeled shopper bike that is the same, when I looked at it I could see the wiring simply doesn't allow it to be rotated.

A quick update. Got a seat post, found a key to fit just need the old battery recelled or rig up another type somewhere on it when time allows.
Thanks for your help.

You can use any battery you want as long as you can fit it to your bike somehow. Anyway, most of those batteries are standard. Look on Aliexpress for "36v rack battery" to see if you can find an identical one. A re-cell will cost a lot more than a new one. Batteries only need re-celling, when they're a special shape and you can't get a replacement.

Before replacing the battery, measure its voltage hot off the charge to see what sort of condition it's in.

If you don't have the correct key, you can normally unlock them with jiggler keys, then disassemble and remove the tumblers so that you can use any key to open it.
