This bike is a monster and I love it!
The 52v 70ah battery gets you to 40mph in no time. The dual motor mode has ridiculous torque and in turn acceleration is outstanding. The bikes suspension is amazing and able to handle potholes at 40 mph no problem. The bike has a very solid build. This is definitely more of an e-moto\e-scooter than an e-bike. I love this bike and would definitely recommend it.
Also, I have dealt with customer service for a few spare parts and I have to say they have been on top of responding to my emails. They are in China so there is a time delay for your emails. Once you understand that and adjust your expectation of when you receive a response email, everything works out perfectly. Eahora in my experience is a wonderful company to deal with.
