TSDZ New Version Tongsheng TSDZ2 Mid Drive Motor Conversion eBike Kit,Torque Sensor 36V 350W E Bike Motor

the good: quite reasonable price, good installation for on my bike(I'm handy), nice display, best switching of power levels assist. nice interface in general. nice wire harnessesthe bad: Torque sensor is insensitive. it takes a bit of pedaling before boost arrives then it's precision is sketchy. better than normal cadence based boost, but not a seamless wonder like say, a Specialized Turbo

This motor with this display is highly recommended for somebody who wants both exercise & the fun of extra power. Have a friend or significant other who is a faster biker? This is how to fix that. It's not perfect, but it senses how hard you're pedaling and gives a helping push in 3 different power settings. The 4th mode has the same power setting as 3 but is highly sensitive to even the smallest of movements.Be careful to check what size your bottom bracket is, though - If you have something wider than 80mm you'll have difficulty getting the motor to mount securely.Note that this motor says 36V(10S, 42V fully charged), but runs happily on a up to (47V). You'll have to get inventive in procurement/creation/charging, but a fully charged 11S battery has a fully charged voltage of 46.8, so it's nearly perfect.Whatever you do, DON'T BUY BATTERIES FROM CHINA - if your battery can be purchased for cheap, you aren't likely to have a good experience (perhaps not even getting the battery delivered).

An Awesome motor less stuff to put on your bike to add weight. I get 15 mi. on a small hover board battery. The setup motor and battery only add 10 lbs. to my ride. Just a great setup, Thanks
