Very easy to install works great

The throttle arrived in ten days.
Works like a charm.

It's perfect

Great bike, fast coasts up hills no problem not sure about battery life yet I dont think battery lasts that long and they want to many photos that I dont know about in order to get a replacement battery.... but I think replacement will die just as quick I just think battery isn't good enough for the power of the bike..... other than that the bike is great !

Switched the thumb throttle to a twist grip. Works perfect and was very easy to replace. Makes it way easier to hold a constant speed, plus feels like my motorcycle. Now I just need the replacement 52 tooth crankset/w left crank to cure ghost peddling. This bike is so fast that I feel I really need that to get a good workout. At 64 years old I need that. Can't say enough about this stellar e bike. Would buy again in a second!
