My Grandfather (which died in last june 2019…) wanted an ebike but less powerful than mine.

So, we made it with a 350W brushless wheel and a 10S5P battery pack (as always soldered from standard 18650 cells). The battery pack is 36V and 14000mah.

He used it for more than 1000km with a pedal assist at about 25km/h.

Now the bike has been bought by a friend and she's using it a lot during holidays.
