Yesterday I also got error 69, 61 and HI. Does anyone know these codes?

As I was afraid, the problem has gotten worse. I must now ride up to 4 min before the engine is behaving normally. It is on and off with err 7. I have also gotten err 30. To me it seems that the engine works fine when it gets hot. I have measured the Volt on the battery and can not find...

I don't have any problems changing gears while pedaling. Keep the cadence over 60 while shifting, and make sure your chain is not worn out. You can also get chains built for e-bikes.

I measured the voltage before charge to 37,5 (after riding 80 minutes). I measured the output voltage on the charger to 41,5. After charge I measured the voltage on the battery to 41,5. When I connected the battery, and started the engine, the display showed "error 7" for about 2 seconds...

no, it's this battery: http://www.greenbikekit.com/36v-samsung-bottle-ebike-battery.html

I have ridden over 1000km without any problems, so why would the battery suddenly have higher voltage? And it is only when I start the engine. Would it be safe to program the controller to accept higher voltage? The voltage peek is only for a few seconds anyway

In recent weeks, my BBS01 has displayed "error 7" when I start the engine in the morning. After a few seconds, the message disappears and the bike works normally. It also happened that I had to ride a few hundred meters before the engine started. Is this a battery or an engine problem? Could...

What tools do I need for the m33 nuts on bbs01?: http://wooshbikes.co.uk/cdkit/cdkit.jpg Is this the one? : http://www.chainreactioncycles.com/no/en/park-tool-fixed-gear-lockring-wrench-hcw17/rp-prod58483

I am also interested in the BBS01. Which of these engines (BBS01 vs CST 205rpm, both 250w ) will have the best performance, and what speed can I expect in an 8% grade hill.

I will definitely go for the 205 rpm version. Now, what happens if it does overheat? Will the motor be completly broken after it is overheated. Or do I simply need to wait for it to cool down, and pedal faster next time?

With this simulator I get similar results: http://www.ebikes.ca/tools/simulator.html But it does not say which versjon it is. Is the 250w and 350w the same engine with different amp? If I set ths simulator to bafang cst and 15amp, It will take me up a 8% hill without overheating. 10% with...

I will use con62 from greenbikekit: http://www.greenbikekit.com/250w-36v-electric-bicycle-hub-motor-controller.html It has over-current protection at 14±0.5A The hill I will ride every day is 4km with up to 10% grade

I'm considering to buy a bafang cst 250w kit. My only consern is if it will overheat on long steep hills? how long hills does it handle? What happens when it overheats? Does it have overheat protection? Will the motor be useless after it is overheated, or do I simply need to wait for it to...
