Overview
Enffe ES2 Ultra is a 20 inch fat tire electric bike with full suspension, a 48V 22.5Ah removable battery, 92Nm of torque from a motor rated to 1500W peak, 7-speed gearing and an NFC LCD display.
Enffe rates range at up to 60 miles on electric power alone and up to 100 miles in assist mode, figures at the high end of what a rider will see day to day. One reviewer who rode 16 hilly miles round trip still had 36% battery remaining, a more useful data point than the marketing ceiling.

- Ships about 90 percent pre-assembled
- Quick replacement parts for a broken reflector
Performance notes
One reviewer described the steepest hills as slow going at 10-15mph on throttle alone but said light pedaling sped things up with little exertion required, calling the power delivery well set up overall.
