Is the Euybike S4 worth $699?

At $699 it is a lot of bike for the money: 1000W peak, a 960Wh battery, full suspension and hydraulic brakes. Only one store lists it new, so $699 is the only new price on record as of November 4, 2026.

How fast does it go, and is it street legal?

Top speed is 28 mph. That is above the 20 mph Class 2 limit in many US states, so check your local rules before riding on public roads or paths.

What range do I get per charge?

Euybike rates up to 60 miles in pedal assist and 45–50 miles on throttle. Real range drops with rider weight, hills, speed and cold weather.

Can I remove the battery to charge it indoors?

Yes. The 48V 20Ah battery is detachable and lockable, so you can carry it inside to charge and lock it to the frame when parked.

What comes in the box?

The bike, a toolkit, the battery, charger, front light and both pedals. You assemble it yourself; owners say it takes about an hour.

How does it compare with a regular fat-tire e-bike?

It is heavier and moped-styled, with a longer seat and more torque, so it suits throttle riding and passengers better than a light trail bike. Expect it to be hard to pedal with the motor off.
