I bought a Senada Saber Pro fat tire ebike and it rides great. I however, like to pedal manually alot without power but unless the ground is very flat this is not easy. I really can only use 1st and 2nd gear for this as anything else is too hard to pedal. Going up hills is almost impossible without power. My ebike is heavy at 78lbs. Are all ebikes like this or should I have purchased a lighter cruiser style?
