Forget the traditional straight frames. It took us countless drafts to create a design that was great-looking, curved, foldable, and overall badass - form and function all-in-one.

We went into detail on the aerodynamics, product design, and feasibility of mass production. The shape of the battery was custom tailors to fit the curved frame well and provide as much as juice at the same time. The "two-piece" design we had made for the frame itself combined with its suspension provides the smoothest ride possible.

Eooou is here to help you conquer any road you take it.

Where's is my bike?????

Bike was never received, emails (the only way you can contact their "customer service") were never answered.
I followed up with the attorney general and law enforcement and the business didn't seem to exist in the City they claimed to be based out of.

I received this link telling me to submit a review.
Here it is

This thing is fast.

Easy to put together, for the front headlight I would strongly recommend a 10mm ratchet. The tools they give you are awesome and compact so you can keep them in your riding backpack or satchel.
So far I’ve had a lot of fun riding this bike, it’s very fast. I’ve never ridden any other electric bikes but this is plenty for me to commute 9 miles to work, I’m almost as fast as the cars on 25mph roads without much effort. The hydraulic disc brakes are amazing, it looks really cool, the tires are great. As a younger guy with an unfortunate hip injury this is a great way for me to get back on two wheels. I may be changing out the seat or at least adding padding(just personal preference)


I'm very excited.Took it out for the 1st time today what an investment! Thanks for all the best wishes. Your friend MJ


my 1st ebik, so far so good. Bike rides smoothly the only change was i had to get a more comfortable seat. Fast in e mode, assy was easy. Purchase the led head light and had a issue finding the power plugging. They had assy it incorrectly and never routed it properly. Took a while but I manage to route and all was well.


I ride it to 10 -- 50 km a day well work up to 50 km a day what would I recommend it this product
