Gear Shift

This feels much more natural than a bike with a cadence sensor, the intuitive torque sensor amplifies the cadence of yourpedaling 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.

When riding uphill or in complex terrain, the extra traction is helpful. The torque sensor handles the abrupt changes in speed and elevation well and never feels like it's going to take off on you when you don't want it to. The need to pedal harder to activate more auxiliary functions may be a downside for those who like to ride leisurely. What sensor you choose ultimately depends on your personal riding preferences. If you prefer a traditional cycling bike experience and can live with the higher price tag, then a torque sensor is a good choice for you. If you prioritize consistent assistance and a more affordable option, then a cadence sensor is better for you.

The S4 Pro Electric Bike AWD is your ticket to thrilling off-roading adventures. Its robust construction and dual motors allow you to conquer rugged terrains with confidence. Explore the great outdoors and satisfy you craving for adventure like never before.

Excellent ebike for the value!

I love this dual motor ebike with a large battery. The ebike has the best suspension and brakes I’ve ever had for the price. I was able to add a bike rack (used a Super 73 rack with slight mods) and mounted a rear lockable trunk box to it. I love that you can password protect the display so nobody can power it up and ride off with it.

Having a blast with the S4 Max

First time e-bike owner, bought two bikes the S4 Max and the classic looking F8 for the wife. We are having great fun cruising Ft Lauderdale beach. Just returned from a 4 hour cruise. Very happy with the purchase. Anya in customer service gives excellent customer service.

S4 Pro Max Dual Motor Ebike

Great bike and build quality, plenty of power and range. All the parts seem to be good quality. Super fun to ride and lights are a nice feature. Seats is nice and comfortable. Super Slow shipping and packaging not the best. Had a few scuffs and marks. Instructions could be a little better detailed with more pictures, Same with user manual. Customer service does responds in a timely manner.

Thanks for the review and sorry for the shipping delay.
Due to the Black Friday event, the shipping was slower and it took 5 days to be delivered.
If it was during normal times, it would be delivered in 2-3 days.
