Converting a hub motor scooter to a chain driven

[pengyou]

I would like to get a e-scooter with a top speed of 50-60 km/h without having to go into 60 and 72v batteries.  5 years ago, most of the scooters were chain driven.  Now, I have searched Taobao, Alibaba and other sides and cannot find one full size scooter that is not a hub motor. 

Has anyone out there ever converted a hub motor scooter to a chain drive?  I am aware of the convenience of the hub motor, but there are some disadvantages also.  I don't want this thread to become a debate over this issue - just a discussion of how to or how it might be converted

Where have you been searching?




So you can easily do that with 25v providing you have the current

Plus there is a ton of brushless motors that will do the job. Might depend on how long you want to wait until you get to 50-60km/h

Maybe you already have 48v battery, but I am thinking of changing to higher voltage due to efficiency.

Anyways good luck

Thanks!  Yes, I have seen the motors/controllers to do it...the  unknown is the actual process of mounting the motor and the chain on the scooter.  I have been looking at several models and see several possibilities but I am hoping to talk to someone who has actually done it before and possibly save me a lot of time, money and embarrassment.  Yes, the motor you have posted would do an awesome job but to get it up to a decent level of efficiency I would need to attach a trailer to the bike and load it with batteries!  Also, I am trying to keep the scooter as light as possible to help with braking.  I am guessing that 36v or 48v at  1,000 watts will be adequate.  If acceleration is not adequate, I have considered the possibility of mounting a high torque hub 350 watt motor on the front wheel...but I am getting ahead of myself.  I was looking at GM's 90 Series BLCD but it appears that in order to get 750 watts I have to pour in 96 volts!  I really like the brushless motor controller advertised on the same page.

Any suggestions for motors in the 36v-48v range, with800-1000 watts?

A 36/48v brush/brushless motor with a 16t cog then like a 24 tooth or something on the rear wheel. I'm not too good with sprocket gear/speed ratios

Anyways I think if you really want good performance upto that speed, you have to consider the weight. I know the videos I've seen on youtube or whatever are not generally 36/48v for the speed you are talkin, more 60v+ even with chain drive

Lol 60km/h is pretty fast on a scooter of any design, is it a push scooter or one you sit on like a motorscooter?

Sit on type, like a motorscooter.
