I have two Trikke T12’s that I want to convert to electricity. I need motor kits that fits the front 12″ wheel. Do you have those in stock? What do you recommend? What battery do I need?
I am in the USA.
Thank You.
we have the motor in stock but we have holidays now. We will back to work after 20th, Feb. For the battery, usually a 6ah-8ah battery is ok. And you can choose 48v or 36v version of this motor. And we can ship to USA.
Hello is 48V version have a faster speed than 36V also what is price of the kit with shipping to USA zip code 61341, I need 2 of these
Thank you !!~
Is this wheel still available? Do you sell a battery for this wheel? It will work on the Trikke T-12 right?
Yes, it is still avaible. The fork size to install this motor is 85mm, the T12 should be ok.
Good night, I have a Trikke T12 Roadster and I want to make it completely electric. Do you have any complete kit, motor, wheel, controls, battery and charger that you have left to do the conversion?
We have 12 inch geared hub motor like this https://www.uumotor.com/light-weight-12-inch-gear-hub-motor.html , which could be ok for it.
This perfect is the only type of rim for 12-inch wheel or there is another model that is not traditional rays and you can also get a kit of this gear hub motor (controller, batteries and charger) and what would be the final price
and it is the only option I have for the Trikke T12 engine or there are others that you suggest me
Yes, we have updated this kit to our dropout size 85mm geared 12 inch motor.
Good morning, could you send me the technical specification of the engine along with the measurement diagram of the same please
how to order?
how much for the set?
please email us at sales@uumotor.com
Hi I’m trying to install a rear motor hub wheel to my city bug kick scooter going from a 250w to a 350w they both are 36v but the scooter has a white wire and the new 350w wheel does not what am I doing wrong please help
usually, it is ok to leave that white wire alone.
Looking for 12″ 24 volt but the space between forks on my application is 70mm…what is available?
The max narrow motor we have is this motor https://www.uumotor.com/light-weight-12-inch-gear-hub-motor.html
Is this the same type of wheel/motor that is used for electric handcycles like Rio Mobility’s Firefly handcycle?
Hello,
Did you ever order this? If so can you tell me how if it worked well?
Thank you.
We are very interested in your product. Could you let us know the Torque rating along with the other specifications like weight, etc?
if mounted on kick scooter
can be the kick scooter used normal way, if is the motor switched of?
Yes. It can be moved as a kick scooter when the motor power is off.
how is the movement initiated? only by switching on?
or must be present any initial kick on movement?
To twist the throttle to drive the motor movement.
what is the difference between front and rear kits the span 100/130 mm only?
or cable lengths? what are the cable lengths?
if i have rear span 100mm, is there any problem with mounting there the front wheel?
Only the dropout size is different. You can install front drive motor to rear wheel if your rear fork size is ok.
