I don't know too much about ebike motors, but I know that applying too much voltage to some types of circuit can burn certain components out. I've since watched a tear-down video of another make of hub, and I have to say the wire used for the windings looked massive though.

Good point. For now on, it's a 24 volter! Thanks (again).

Understood. Many thanks for taking the trouble to reply. And finally, the scores:- Cyclotricity technical support - zero. Ebikes forum - zilch. Pedelec forum - loads.

OK. But is the gearing specific to the 26" rim it was built into?

It goes. I'm only wondering how I should advertise it when I come to sell it on. Many thanks.

... this hub please? Bought secondhand off ebay as a 36v 250w. However a similar hub currently listed there is advertised as 24v. https://drive.google.com/file/d/1N6vxJ9AHNN4rmvAptEt5PBFHDEaoDeTM/view?usp=drivesdk https://drive.google.com/file/d/1Mk-sxBx-sbHAERvHKhH_1Jc4-rfnGlM7/view?usp=drivesdk https://drive.google.com/file/d/1MsqkjMn5AgH0f-of0qPBWxKgeirVzTDq/view?usp=drivesdk

Bingo. https://drive.google.com/file/d/1N882pt8GRAEQrNUyOMj_d33N0QgIPt9A/view?usp=drivesdk https://drive.google.com/file/d/1N0_SoU0FBEVqBDAmJ1xBvYoSsG7Pd4VH/view?usp=drivesdk https://drive.google.com/file/d/1MiZcAKBgOU3nGOX-Ibsjxm-L9_QxlNtU/view?usp=drivesdk

Ah, it would appear I lied when I said my hub was unmarked. And the rotation test suggests geared. Anyway here it is ... (fumble, fumble) No it isn't. Yet. Hold the phone ...

A lot if useful information here. Many thanks all. My hub is also unmarked, so how can you identify the type please?

I'm wondering if I can build my existing Cyclotricity 36v 250w front hub (built into a 26" wheel and bought in Sep 2018) into a 20" rim. A) Cyclotricity's literature states that their 36v 250w hubs are geared, but I understood that mine was direct drive. Can anyone confirm this change, or have the hubs always been one way or the other? B) Is there any difference between the hubs Cyclotricity build into 20" and 26" wheels? If the hubs used to be direct drive, does this make a difference? C) Vague question - is there any reason why I shouldn't be able to build my existing hub into a 20" rim? Yes, I've tried contacting the company's technical department. It's for a cargo bike, if that's relevant. I've already installed another ebike front wheel (bought secondhand off ebay) but although this has a julet 9 pin connector and works 'ok' with the controller, LCD display, and battery, the speed displayed is wrong (inspite of having updated the wheel size). I'm thinking the pin configuration is a little different to the Cyclotricity gear. Many thanks ...
