    Great bike

    Tried it for the first time today and it was great ! It’s fast !For reference I am 5’6 and I can still lower the seat more. I would say not for someone shorter than 5’1.Pretty easy to put together. And I am impress on how long it stays charged !I have been looking for an electric mountain Bikes that wouldn’t be to tall and this one is perfect for a woman I think. The tires are about 2”5 so not fat tires but handles ok in the sand (not deep sand!). We did 10 miles and Nothing has broke so far, looks like really good quality.

    Strong Sturdy Frame

    Impressive ebike with speed and durability.

    I was really impressed with the ease of assembly. The tools are supplied and it was very easy to assemble. The bike is solid. Looks like it can really take a beating. Top speed is accurately advertised and the pedal assist will get you to top speed faster especially when going up hill. Electronics are great and the seat is comfortable. I am 6’5 and 275 lbs and the bike carries me well. Very enjoyable ride. Glad I made the purchase and highly recommend this bike to anyone in the market.

    Mostly Happy with it.

    The bike showed up on time and no damage to the box from shipping. Everything was packed well. My only issues have to do with the breaks. They were adjusted very poorly and needed to be taken into a shop to stop from rubbing. While at the bike shop, the person working on the bike said the break pads are not lined up properly and only haft the pads make contact to the rotor. This makes no sense and causes breaking issues. Not looking forward to bring it back to the shop and paying a high hourly rate to have them figure out how to make the breaks work properly. Other than that, I’m cool with everything else.

    Grey bike

    The bike is great but the most important is the staff. Whatever issue the bike has, they are willing to help. Always respond and ready to help. Overall I’m happy with the bike.

    I upgraded the brakes to hydraulic brakes, everything else works as advertised.
