Questions about Electric Bikes
Hi to all forum members :) I´m so sorry but i have soooo many questions :D (i´m trying to make a new vehicle (patent) but it will require some hard core info)
1.1)Weight - i would like to know the weigh of all motors if someone has found a list OR at least the weighs of motors that would go 20,30,40 [Km/h] with 100[Kg]/220[lb] person
1.2)Can those weight less than 3 Kg?
1.3)Do this motors have breaks and gears or they actually do everything by power direction (slowing,speeding,stopping etc...) ?
1.4)Why are Wattage AND Voltage differences "needed" ?
1.5)Can 250W/48V Engine be better than Higher Wattage but 12V Engine ?
1.6)Would additional gears on Ebike work? Ok lets just say i can change gears for 1x to 2x Speed so if it goes 5 RPM/Sec it should go 10 RPM/Sec (to the wheel) and reach double speed (or lets say a have motor attached to pedals)
2.0)Batteries (searching for low-weigh batteries but not a lot more expensive too)
2.3)do more voltage batteries weigh more than more wattage batteries?
2.2)how much would batteries that can last 2 Hours weight if they allow me to go a) 20[Km/h] , b) 30[Km/h] , c) 40[Km/h]
2.3)Can those weight less than 3 Kg?
2.4)What would be the recharge time for that 2 Hours?
ANY help will be appreciated :thumb:
