Proud owner of a Big Sur Sport
I just purchased my Big Sur sport and have been riding it daily! I just can't seem to get off the bike. It's so fun and easy to ride. Very powerful as well and awesome breaks! AIMA did an awesome job on this one~ i'm planning to purchase a secondary one for my son.. if you don't like the big wheels, then the 20 inch fat tires for you. Easier mobility and you can almost ride over anything. The traction is superb.

Aima Big Sur Sport Ebike
I bought my electric bike Aima Big Sur Sport Ebike, a year ago, and I ride it every weekend with my friends. I couldn't have dreamed of a better bike — it's absolutely perfect. I researched many different models before making a decision, and I can confidently say this is the best e-bike out there. The quality is outstanding, and the ride is smooth, powerful, and reliable. The company is also fantastic — anytime I had a question, they were quick to help…
