Great bike for a decent price

Only have a few miles on the bike but seems decent. Has good power with the electric motor and battery life seems good. The front forks are ok at best and tires seem ok. I’m not sure how it would hold up against extreme mountain biking but for someone just wanting a cruiser it’s perfect. Never received my free gift though….

This is one quality built bike.

The packaging was top shelf. Everything was wrapped and secured in the heavy duty box. Not a scratch anyplace. Take your time assembling it and go by the directions. The welds on the frame were some of the best I’ve seen. Everything fit as it was suppose to.

Improvements: The crotchbar too high. I am 5 foot five inches or 65 inches , Would like a m2 step through
too tall for 5’5 person

I love this bike. The features are awesome. Everyone stops us when we are riding to ask about it. HOWEVER i am 5foot 5 inches tall and have a VERY DIFFICULT time touching the ground when coming to a stop, which in turn, makes it also difficult to try to hop back up and start pedaling again. It makes me scared, especially when there is alot of traffic. I wish they made a step through or “womens” model with a lower crotchbar for the M2. I also have to tilt the bike down a bit to get on, which isn’t terrible but the bike is heavy sometimes after riding and having to get off and on to walk. Besides that we love them. We also bought bigger seats and cargo bags.

First Ebike

This is my first Ebike. I enjoy riding it, the bike handles well and with the assist makes the ride enjoyable. The M2 with the larger tire rides nice with the tire helping the shock system. The seat is comfortable for the length of rides I have been doing. The charging system lasts a long time and doesn't take long to charge it up again for the next day. Great bike for the price. I would recommend having help when putting it together to help hold the bike upright. Easy putting together with online directions. Have fun

Improvements: Battery amp needs to be better/higher
Quality and balanced

The bike has lots of torque. Hills are a breeze. The balance of the bike is perfect. Build quality and components are very good. The battery is too low "ah" for what the bike is. I wish they would offer a higher "ah" than 11 or 13. The labels and online say different all over. The ah needs to be above 19 for this type of bike. Overall I am impressed with the bike. I will be looking to get a spare battery or a higher "ah" that will fit.
