Very Powerful

I've put 250 miles into this bike so fat and I love it! It delivers fantastic value for the build quality. Pro tip: hold up and down buttons and the same time and increase the speed limit to 40kph in the settings to unlock the full power of the bike.

Well Built & Complete Joy to Ride

I waited until I hit 100 miles on this beauty before writing this review. My riding buddies told me I couldn't get a quality ebike for under $3k. Absolutely the wrong advice. The Supreme is amazing in every way. Well built, close attention to detail and a complete joy to ride. I would highly recommend this bike to anyone looking for a great ebike experience.

Truly Excited

I am very excited and happy with my new ebike. Love the speed, must admit I do love to go fast. Was a bit unsure of my final decision but Really Good Ebike was a great help and it has worked out great. Will surely be back.

Really Good Fat Tire Ebike

This ebike has some really nice features, you totally get your money's worth. It has great power but also great control, what I love most on this bike is the automatic motor cutoffs. With all that speed and power it is a great feature to have. So far I am really enjoying my new ebike. Bonus points for having it in stock and shipping it so quickly.

Great Battery Life

The battery life on the BAM Step-Through 750W Electric Cruiser is amazing. I’ve had it a couple weeks and use it every day. I’ve only had to recharge it once and even then, I probably still had a couple days left to ride it.

Do you need an affordable fat tire electric mountain bike which does not compromise on power? Do you want a long-lasting battery that can take you up to 45 miles on a single charge? They we suggest you check out the new EW-Supreme from EWheels Ebikes (formerly known as the Bam Power Bikes Nomad Supreme).

EW-Supreme Ebike Description

Whether your travels take you through the urban jungle or to wilderness trails, the fully-loaded EW-Supreme is the electric mountain bike to get you there in style. The EW-Supreme features a 750W rear hub motor with 80 Nm of torque, which will help you power through sand and snow alike. This massive motor is paired with an equally robust 48V/14Ah downtube battery, with Samsung cells and a USB charge port.

The EW-Supreme (formerly known as the Bam Nomad Supreme) comes with a 5-level Intelligent Pedal Assist System (PAS), which you control with a left-side button pad. As you increase the pedal assist level, the motor will push you along, as if by magic.

You can also use the 7-speed Shimano Altus gears when pedaling, with or without the motor engaged. And if you want to ride without pedaling at all, just give the twist throttle a twist, and off you go, no pedaling required.

A convenient interactive back-lit LCD display keeps you informed on your speed, distance and battery life and can even charge your phone! An added benefit is the front and rear LED lights that make sure you can see and be seen when the going gets dark.

The EW-Supreme lives up to its name with its all terrain capabilities that’s ready for anything from the forest to the desert. Up front, you get an adjustable front suspension fork with 80 millimeters of travel along with large mechanical disc brakes that provide excellent stopping power whenever and wherever you need it.

The EW-Supreme also features Kendra Juggernaut fat tires with a dual compound tread that provides a surefooted grip no matter if you ride on pavement, dirt, sand or snow.
