I’ve been very happy with the quality of the bike for the price. Delivery was fast, and the bike arrived in perfect condition. The free accessories make the ride even more enjoyable!

Thanks for sharing! Glad you’re enjoying the bike and the extra accessories. Enjoy the ride!

Gret Bike And Lots Of Fun!

After researching a lot , I decided to pull the trigger on this model. Came packed well and was easy to assemble. Have run about 35 miles so far and initial battery at 5 and maybe 20% pedal I was able to get 20 miles out of it. I am now trying to do a random mix of about 40% pedal assist and 60% just electric to see how long the battery lasts. Very fun bike and hope to buy another for my wife.

Honeydew Green / Ebike Only

Love This Bike
