Whats the smallest motor that can probably move someone, for instance 49cc gas motor can move the bike and a person on it.
Can 1hp or 3 hp electric engine have enough power to move someone? Not on a bike necessarily

Answer by Samuel
Your question is to vague. Even the smallest motor could move a person if geared correctly, although very slowly.
1hp = 735watts. So if you can pick an application that needs a 1hp gas engine then an electric motor that uses approximately 735watts will be roughly equivalent. Not counting friction and resistances of coarse.
What do you think? Answer below!
For comparison, the 49cc 2-stroke motors put out around 2HP. This will get a light load like you and your scooter up to around 35-40 mph.
ReplyDeleteTo cruise comfortably at 65mph, you need at least 10 HP or so, as the power required to overcome drag due to air goes up as the CUBE of velocity.
500 watts = 1/2 horsepower.
ReplyDeleteElectric mobility scooters and wheelchairs have about 1/2 horsepower motors.
Many recreational and commuter scooters also have 1/2 horsepower motors.
It's about gearing. You could easily use a 1/10 horsepower motor if you geared it to run a couple of miles per hour.
