We just got these trikke 12 from a guy out here near Venice beach, like 15 of these T 12 scooter and we are going to rent them out but everybody wants them powered, so thats why im trying to get the infomation to convert at least 5 at first see how hard it will be.

You have photos of completed kit please
If you like disc braking version, we can customize it for you. It is ok to make a dropout size 100mm motor with disc braking bracket.We will send you the photo via email.
oh good info,, this is the motor i need for trikke 12. can i put it on the 2 back wheels with one controller or 2 and can i still connect the disk brakes that comes with it to existing trikke back wheel hub area. i think the back hub is 4 inchs space 102mm.
this motor has no place to add disc brake to it , it only ok for V brake. If you want two motors, you need two controllers, we have no dual drive controller yet.
Tony what is the V break, and if i did 2 kits with 2 controller do you know if one wheel will push faster than the other and i will feel it when driving the scooter. with you experience with working with these motor powered wheels, . do you think it would work.
the hub does have brakes its just not a disc brake right? and i guess i would need 2 batteries also right.
Hi could you let me know diameter of motor? just motor

Any chance to make it maximum efficient on 82V?
What about use it as a front wheel?
Any chance to get disk and support with this wheel?
Sorry, the max voltage is 48v. It is ok to use as a front wheel drive. We can add a disc braking base to the motor so that it can support disc braking.
Hello,
i have some questions: Does the motor have a disc brake mount support (6 hole type)? Is it possible to use a 12″ x 1,75 tyre? Thanks
Hello Christian,
We an use a extra flange to make the motor using 6 hole disc braking. Currently, the tire is only one type. You could use the 1.75 tire at your side.

Hi Paolo,
could you let me know what size of the motor do you need? this 12inch motor? We have 100mm fork size front wheel motor 36v 250w version.
Interested in 12 inch ~150 watt 3phase brushless hub motors as well as brushed dc.
Hello John, what is your application? why so lower power and what is the dropout size of the motor you reqestion?
My application is driving a robot, I don’t need any more power since my payload is 40 to 80 lbs across 2 wheels. I need about 13 Nm of torque.
Is it possible for a 12v Brushless version.
How about having the axil only on one side like some of the smaller scooter wheels.
John
Hello John,
It is ok to make single shaft motor, but for the voltage, we only have 24v version.
