12 reasons not to buy

The Defender S is very heavy at 84lb.
Experts say the weight and power in the front wheel make it difficult to start turning or change direction once turning.
One tester complains that the throttle offers too much power.
An expert describes the front and rear suspension as on the springy side.
EUNORAU doesn’t provide guidance on setting up the rear suspension, according to one reviewer.
Testers and owners struggle to fit the battery cover. EUNORAU responds with video instructions on how to do it, which requires a wrench.
In one PAS 5 range test with both motors, a reviewer gets just eight miles of paved riding, the worst performance of all e-bikes they’ve tested.
With its 1500W nominal power, the Defender S exceeds e-bike classification and can only be used on private land.
The “lower-end” unbranded hydraulic disc brakes return below-average stopping power in testing.
The display is hard to read in direct sunlight.
One reviewer thinks the cabling is messy.
EUNORAU owners report problems with customer support, missing parts, and damage upon delivery.

Bottom line

The EUNORAU Defender S is a full-suspension, fat-tire e-bike with two hub motors and capacity for two batteries. Experts laud the impressive performance on hills, rocket-like acceleration, and “cushy” ride. They also appreciate the capability off-road. However, the bike is very heavy. Experts find it difficult to maneuver due to its total weight and the extra weight and power in the front wheel. Additionally, range is laughably low when using both motors, braking performance is poor, and it’s illegal to use on public roads. Overall, the EUNORAU Defender S earns relatively low marks from reviewers who find it “expensive” and unsuitable for inexperienced riders.
