There are 2 kinds of Kysmo bikes floating around. One is the older steel frame model. Its a bit on the heavy side but well built. Delivery guys use those year round. Typicly for a 180pnd person you get 17miles at 17 mph. The new versions are now aluminium frames. About 350w. A newer motor and an all around upgrade.
The great thing about the kysmo brand is they come with a lock for the battery. Everything is in the battery box, controler and all. They are great in the wet weather. You should have no problem keeping them locked up outside year round. All that is required is wrapping a plastic bag over the throttle. Every thing else is water proof bar submersing the bike in water.
The older steel models sell for around 800$. The new model is just over 1000$
Considering the quality of the bike is around that of most entry level bikes at 300-400$ its not a bad deal at all. I own a 48v/1000w kit. My 20ah battery alone was 600$ with shipping for a lifpod(only battery worth a crud). The motor and gear was around 340$. Top speed is 32mph on flat ground and I typicly get around 28 miles at 20mph or 20ish miles at 30mph on a flat ride. Throw in the cost of my hybrid at 400$ and Im well up there in cost. The kysmo is a great deal for people under 220 pounds that dont want to break the 20mph barrier.
Best bike per $$ that is legal as in e-bike imo. My kit is not legal in any state because of the wattage.
