EUY S4 Pro Max Offers Dual Motors, 30 MPH

If you are looking for a dual motor ebike that eats hills for breakfast consider the e-moped style EUY S4 Pro Max. This ebike is an evolution of the S4 single motor I reviewed last year. Its a blast to ride though I do feel a bit tall for it.

The S4 Pro Max is powered by two 1000 watt motors that peak at 1500W each. Battery comes in the form of a 52V 30AH battery that saddles right inside the frame. Each motor has 96nm of torque.

The battery is a Samsung/LG battery, with 21700 cells This 1820Wh battery effectively improves the range, stability and safety of the S4 Pro Max E-Bike. On a single charge, it has an electric range of up to 40 miles and a pedal-assisted range of more than 80 miles. 

It also features a torque sensor for a better pedal experience. But for me I am too tall to pedal a bike like this. For me its throttle only.

Here’s how EUY describes the torque sensor vs cadence;

This feels much more natural than a bike with a cadence sensor, the intuitive torque sensor amplifies the cadence of your pedaling efforts. Pedal hard and you get maximum boost. Reduce the intensity and the boost system will reduce the intensity accordingly, no more ghost pedaling. Torque sensors are also more efficient than cadence sensors because the power provided is based on how hard you’re actually pedaling and updates in real time. This efficiency usually means matching your natural rhythm to conserve battery life and extend range.

The S4 has a payload capacity of 400 lbs. You can easily switch between rear wheel only, front wheel only or dual motor riding from within the display vie a button on the control pad. It also features hydraulic disk brakes, front turn signals and a cool LED taillight with neon colors.
