9 reasons not to buy

The Ranger's non-integrated taillight is dim and doesn't have brake activation.
Out of the box, this bike can reach or exceed 28mph using the throttle. This can be adjusted in the app to avoid riding illegally.
The smartphone app requires internet access to work. Testers and users report the app regularly losing its connection to the bike.
This bike has only three PAS levels, two fewer than most e-bikes.
Other than removing the battery, there’s no way to stop someone turning the bike on.
The website states the motor has 85Nm, but elsewhere, it says “80 torque.”
The Ranger’s high 84lb weight makes it hard to lift or transport.
PAS 1 reaches 15-19mph. Combined with the on-off throttle, this makes relaxed cruising difficult.
An owner reports electrical problems with both of their Rangers.

Bottom line

OKAI’s Ranger EB50 is a burly, fat-tire e-bike with some curious tech. Testers praise the side lighting, smoothly integrated, intuitive touchscreen display, and stable, comfy ride. The bike’s speed, acceleration, and hill-climbing also impress. However, PAS 1 is too fast, and the bike is very heavy. Mechanical brakes and the non-integrated taillight are disappointing at this price. The app requires internet access to function, and the Bluetooth connection is unstable. Ultimately, the Ranger EB50 is too heavy, basic, and incomplete an offering for this price point.
