changing subject - your electric bike , i read its still going strong after 100 miles , do you think the range will be effected if you add hills ? i cant work it out whether constant out put on flat will be lesser or greater than power up hill and coast down - interested to know ? and could you in theory have a dynamo to click on when going down to trickle charge battery ?
We are nearing 100 miles with quite a bit of battery voltage left. Im expecting to see a quick drop off nearer to flat.
Hills will have a greater drain on battery especially if you want to go up quickly. The system works by multiplying the riders power EG rider produces 100W. lets say assist level is set on 1.5, so electric motor makes 150W = 250W total.
She currently has 6 assist levels with top level 2 times rider power. I. can add upto 9 levels and set the assist on each level.
For a bit of fun raised the speed limit, when I tried the bike I was flying along in a upright position with little input, the motor was assisting me with 300W, so maybe 450 W total.
Wife doesn't produce much long distance power maybe 120-150W but the additional help allows her to cruise 14-16 mph and not break into a sweat.
The good points is, its easy for her to get back upto speed from junctions, so it doesn't tire her.
It was comical the other day I was drafting her on this road into a headwind, young man roadie cyclist came by doing probably 19mph we were able to stay with him on a drag but dropped when road flattened out. I was pedalling quite hard to stay in the draft on my single speed
There is no regen on downhillsf the battery unfortunately. This system drops power to zero if freewheeling so no unnecessary drain
