Question: Does it twist for forward and reverse or require a switch?
Document: overly expensive shipping and got it with a stripped screw and broken led lights i am now figuring out how to return it save yourself a huge head ache and go to a scooter store.
We have  only had it a few weeks but it fit good and works well so far. Easy to install.
This throttle was put into an eZip e500 electric scooter. My son's friends broke the original throttle and so it needed to be replaced. It was very easy to disconnect the old throttle and replace. We just needed to have the correct Allen wrenches and a phillips screwdriver. Just popped it in and off he went!
Original throttle broke when my sons smashed the scooter down. The product arrived quickly and it was super easy to install. I am not a mechanic nor do I have those type of skills and it was no problem!
I installed this Throttle For my boys Ezip E-450 Scooter and it works great now. no instructions but easy to figure out
I bought this for a replacement and of course it works, I am not sure if I like a throttle with a brain it take's up energy.
Everything bout it is meeting my expectations. My dad takes it to work and has had no problem with it so far. :)
As it worked very first time I chose this rating.The other part namely speed controler also did good work .My scooter is running now.Thank you.
