Re: A couple more Norcos

I live in a world where innovation, design skill and craftmanship are valued. Not everything can or should be broken down to base material cost and compared to cheap alternatives - although if you do, there is still value here, where you add the original frame, design, fabrication, welding and paint...

looking at the AJP PR3 - it has a seat height of only 33 inches. In that case, what height is the Sur-Ron's seat?

Congratulations on achieving your goals. In the preorder offer, can you please consider supplying a small batch of developer kits? For example, supply frame only with motor, rear hub, and drive sprocket. Might help those that want to support LMX but struggle with the full cost of 4583€.

Re: FUTR Beta with Lightning Rods Mid Drive

PRW what are your thought on the middrive two months later? Does your Phasor hub bike exel in any way or do you just ride this now? the middrive/Beta is great on tight trails, repeated steep hill climbs with tight corners and difficult lines - not only because of the middrive, but because the Beta ...

Re: Voltage drop vs AH

Samsung INR18650-30Q Graph.png 53.8V / 14= 3.84V Assuming the voltage measurement were taken at rest. So from the graph, using the top line, it looks like about 1.1Ahr per parallel cell x 7p = 7.7Ahr used. This is going to be a very crude estimate as the voltage depends on discharge current, temper...

Voltage drop vs AH

So... can you calculate amp hours used from the starting and ending voltage on a trip?
For example from yesterday, my wife did 34.3km (21.3 miles) with a 14S7P 30Q battery, BBSHD. Starting voltage was 57.4, ending 53.8.
How do you turn this info into ah used?
