SOLD - 2 Tongxin kits + 1 Ping battery + controller
Now sold - thanks to everyone for interest
My electric biking days are over for the time being (because I nowadays do lots of non-electric cycling) and I need to tidy up my garage, so I'd like to sell my stock of kits / bits and battery
What I have is this:
Kit 1
- Tongxin motor, 260 rpm, for 100mm dropouts (ie normal front forks) laced into a 700c rim (Mavic). Schwalbe Marathon Plus tyre (good condition)
- e-Crazyman sensorless, brushless 36v controller. Unused. I bought this as an alternative to Tongxin’s own ones and asked Keywin (aka eCrazyman) to build it up with robust mosfets to make it more resilient than Tongxin’s own ones. Has pedelec sensor.
- 1 set of cut-out v-brake levers
- 1 thumb throttle
- 1 cut-out handlebar switch
- Torque arm (bought from an eBay supplier in the US, but not used)
Altogether this lot cost about £320
Kit 2
- Tongxin motor, 36v/260rpm, laced into a 700c rim (Mavic). This is a rear motor with a screw thread and a 5-speed freewheel (NB it won't work with >5 speed as there isn't enough axle length. I actually ended up using it as a front motor by spreading the forks and it worked fine)
- Tongxin sensorless, brushless 36v controller. From a 2009 batch (via JohnP) when reliability appeared to be better.
- twist throttle
Cost of this was around £220
Battery
1 Ping LiFePO4 battery. 36v/10Ah. (+ charger)
I bought this battery 12 months ago, directly from Ping. Cost was around £260. It was mainly used on a week-long tour of the Netherlands last May, plus a couple of day rides around that time. I then used it on the Ching Challenge in Exmoor last September (when it performed extremely well). It has not been used since, but I have kept a watch on it to see that it did not discharge. As is documented elsewhere on the site, these batteries do have a longer life than other chemistries and I believe it to be in very good condition.
I have fitted it with powerpoles for connection to a bike.
Extra controller
1 controller for a brushless motor with sensors (eg Bafang or similar - not for Tongxin). eCrazyman, 36v. Unused in its box.
I'd prefer to sell everything together, and it would be a bit of a pain to post so collection is preferred (London). The whole lot cost me about £800. As the parts are not new and, to be honest, I've had a lot of fun out of them, I would accept £400.
Please let me know if you’d like more details or photos of any particular bits
If you’d like more background do ask. Also, all of my projects are documented at great length on the forum. If you are interested, do have a search in my old postings, or let me know and I can dig out some of the relevant threads.
I'll leave this up here for a little while. If there are no takers I'll auction off the bits separately.
