Aima Big Sur Features
Torque Sensor – One of the latest e-bike innovations, a torque sensor sees how hard you pedal in real time and matches your input power using the motor. This leads to a safer and more intuitive ride, as well as conserving battery life.
Full Color Backlit LCD Display – View essential stats at any time with a bright and daylight-ready full color screen. Choose between several different themes to see your speed, battery life, pedal assist level, and much more.
Fender & Rear Rack – An MIK HD rear rack comes standard, allowing for endless customization possibilities. Plus, fenders come pre-installed to ensure you’re protected from below while riding in any weather conditions.
Suspension Fork – With up to 80mm of travel and adjustable preload and lockout settings, our suspension fork eats up everything in your path, assisted by Big Sur’s 4″ wide tires.
Walk Assist – Walk your bike alongside you, up a hill, or anywhere you need to with Walk Assist, which allows the bike to maintain a constant ~2-3mph based on your walking speed.
Controller Compartment – Big Sur’s controller is mounted right near the pedals, allowing for easy access during repairs and maintenance. Plus, this mounting style allows the controller to utilize the entire frame as a heat sink, greatly improving safety and performance under load.
Flat Position Welding – We’ve taken great care and utilized some of the newest aluminum welding techniques available on our frame, which comes with a lifetime warranty. These techniques allow the frame to maintain its structural rigidity while also appearing flat and smooth.
