Aima Big Sur

Aima Big Sur 20" - Electric Fat Bike

Experience the return of everything you adore about the classic Aima Big Sur Electric bike at Bike Attack Electric! Now featuring 20" x 4" fat tires, the Big Sur Sport is more compact and lighter while maintaining the same level of enjoyment and performance as the Big Sur 26", if not surpassing it! This bicycle preserves the original's class 2/3 rating (achieving top speeds of 20mph) and upholds its safety features, such as substantial 203mm brake rotors, LG 21700 battery cells, and complete UL2849 certification. With the AIMA Comfort XL seat and an MIK rear rack as standard additions, the Big Sur Sport ensures an equal caliber of power, comfort, speed and smooth operation as its larger counterpart.
