Robby, you are very helpful and an excellent communicator! I am sure your 'can do' attitude will win you many friends here on this forum and many new customers. When your engineers look into this, I'd like to recommend that they implement a 'battery lock' function via the mobile phone as passive...

Yes, CAN bus is OK. Bluetooth is excellent. Does it make the battery much more expensive? how much more on cost do you think?

yes, Robby. A data port that can communicate with serial interface with a PC. I'd like to log charging dates, charging current, load and individual cell voltages.

there is a market for legal high speed e-bikes, perhaps up to 40mph two seaters where they can compete with cars. This bike may be very useful for someone who is interested in going into business making these. The owner did point out that 'The license plate is where the value is for a UK buyer'.

I agree that quality control in Chinese factories is weak but the fact remains that cwah's motor has done about 700kms without problem. It's only prudent to rule out other factors before jumping to conclusion. Cwah reported that the noise is once per revolution suggests that the noise is somehow...

Robby, do you have intelligent BMS with data port for data logging?

the woosh battery kit includes charger. There are two prices in their online shop: one for UK and one for EU (at the bottom of the online shop page). For EU: 500W BBS02 + 36V 15AH battery, including delivery to EU address: £379 + £345 = £724

I don't think you'd need a generator inverter although I can imagine in remote places, it may give you some re-assurance. Assume that you want to do 150 miles a day. That would require about 1kWH. Using the best cells at present, that would be 10S8P of NCR 3400mAH. At 50g per cell, the custom...

No problem there, look for 'pure sine wave' on the generator specs. They are computer controlled. Most modern generators have this.

New low cost Woosh CD kit:

@d8veh - wow! there is even room in your trailer for packing a tent, food and fuel. How noisy is the generator in that trailer? can you run the generator while riding to continuously recharge your battery?

Robby, how much you sell this battery with 10S4P NCR 3200mAH for? Also, can you modify the case to add an e-bike controller inside?

Robby, does your company make custom battery cases? I think NCR cells are slightly better, better quality control, fewer defects.

I don't think the noise comes from the needle bearing in cwah's motor. These bearings are specified for 10,000+ miles. If this goes, the one way clutch would slip a little if you push very hard on the pedals. His problem comes from somewhere else. Cwah, you should refit the kit to make sure...

irregular time to cutouts could be caused by a faulty throttle.

throttle should be made illegal because it turns a bike into a mobility scooter.

I think the general rule is, if you are not certain, make it plural and omit the apostrophe. Write it as carpenters vice. At least, everyone will understand. After all, the apostrophe was not introduced that long ago, it was invented for the benefit of the printers.

that's about the right price if in perfect condition, although personally, I would not pay more than £250 because it will be difficult to get spares or support. veliac.es used to be the manufacturers. I think they've gone under. I've seen them in a couple of shops in France about 2 years ago...

AFAIK, woosh sold a lot of bikes to France. Also, you can unplug/switch off the throttle on all the woosh bikes except on the Sundowner and the Zephyr CDN. The police in all the EU countries where I've been to don't even look at ready made e-bikes. Perhaps the reason is that they presume that...
