Hello,

I'm looking for rear wheel kit to travel 1 mile up hill from my house to work, elevation is 40m.
What I found till now is kit from amazon 36V 500W and 10s 4.5Ah battery.
Could 3x 3s batteries be used instead ?

I would prefer 48V kit with pedal sensor, could you let me know such kit from webshop within eu ?
