how to build a electric bike using my old MTB mountain bike ?

Q. loading: 100 kgs, speed: 70kph, and want to climbing. please tell me any ideas, thanks!


Answer
hi, i recommend buy a electric bike conversion kits to convert it . But please note some notes,
1. Does the motor fit for your bike ? I mean that you need to measure your bike drop out , and confirm it with the seller .
2. Confirm the right wheel size with your seller . You can confirm your bike wheel size according to your bike tires , such 26 x .... , 700c x ... It means your bike is 26inch, or your bike wheel is 700c .
3. The speed 70kph is very fast, so you need to make sure that your bike frame is good enough .
I recommend that the 1500w hub motor for your bike . Its speed is about 70kph with 26inch wheel, and the controller max current is about 40 amp .

Electric Scooter or a Mountain Bike?

Q. I'm a soon-to-be community college attendee, and I can't decide whether to get a bike or electric scooter for basic transit in the hillish areas of Reno. I loved my bike back home, but it was pretty much destroyed by a reckless friend of mine after I let him borrow it (he's making a speedy recovery). I don't have near enough for a car yet, and my license is invalid since I just moved. I just need something reliable and good for short-medium range transit around town.


Answer
Why is your driver's license invalid? Anyway, you need a driver's license for a motor scooter. And anyway, a mountain bike isn't the best commuter bike, a road bike is. If you're going to be riding gravel trails as well consider a cyclocross bike. If you primarily mountain bike on rocky singletrack a mountain bike can still be a commuter but you'll never be as efficient on roads as you would on a road bike. Of course the bicycle, whichever kind you decide you need, is the most efficient and cheapest form of transportation.
