Koa Rev+ 26” Electric Fat Tire Bike
Retrospec had one goal in developing this bike: Make the best fat tire e-bike on the market under $2,000, and they put their all into every single detail.
Koa Rev+ has:
• An integrated battery with LG cells and the same or more juice than all of our competitors
• Tektro hydraulic disc brakes with e-bike specific rotors (unlike the competition)
• An easy-read color display
• Puncture-resistant tires
• Major packaging improvements to ensure safe transit/delivery, and so much more.
In the end, they've created an e-bike that goes the extra mile, both literally and figuratively.
