2018 Key Improvements

New and Improved Battery:

We upgraded the 2018 batteries to 14Ah and we're using the new Samsung 35E cells, which are super energy-dense and reliable.

*The 2018 battery is not compatible with 2016/2017 models. We may be offering the 2016/2017 style battery with the upgraded 14Ah cells in the future.

Front Suspension Fork:

Our custom RadMini suspension fork has 60 mm of travel, preload adjustment, and lockout. Combined with the fat tires, you're in for one smooth ride. (This feature replaces the front rack found on previous models.)

Front / Rear Rack Mounts:

Our 2018 lineup has a brand new line of universal racks and baskets that are compatible across all 2018 models. The 2018 RadMini no longer comes stock with a front rack.

New Color Scheme:

The classic black and white have been improved with fresh styling and accents.

Description

Performance

Performance

Spend less time charging and more time riding.

Our specialty is battery and electric motor technology and we understand you want to commute to and from work, climb hills, stand-your-own in traffic and get to your destination faster. We have what you want and it's 48V and 750W of clean power. The RadMini gets an estimated range of 25-45+ miles per charge allowing you to get a full day's worth of use without having to stop to plug in.

48V and 750W of power results in an electric fat bike capable of tackling terrain and going the distance unlike the lower power and voltage options on the market.

Unlike other electric bikes with low capacity 36V batteries, we splurged on our battery packs because we know that this is the single most important component of any electric bike. The 48V 14Ah battery packs a punch and has the capacity and range to be there for you when you need it most at the end of a long ride. At only 7.7 lbs, this is one of the lightest and most energy dense battery packs ever supplied on an electric bike. Combine that with the external battery meter and easy removal for charging and transport, you have a feature rich battery pack you can depend on.

Brushless Geared Hub Motor

A hub motor is an electric motor incorporated into the hub of the wheel. These motors are compact, maintenance free, and discreet. Hub motors are the most common drive method for ebikes today and offer a number of advantages.

We applied our experience with years of taking ebike motors to their limits in high-performance applications and have outfitted the RadMini with a powerful, lightweight, brushless geared hub motor specifically designed for use with our 15 amp continuous motor controller and 48V battery pack.

Key Points:

The motor is mounted in the rear wheel which increases traction when starting on hills and provides greater stability compared to front hub motors.
An internal planetary gear provides ample starting torque and a high top speed while keeping the weight of the bike low for floating over snow and sand. Geared hub motors have internal gears which allow the high speed and high-efficiency motor inside to match the speed of the 20'' wheels.
Geared hub motors typically weigh around 50% less than a direct drive hub motor with similar performance.
The motor also includes an internal freewheel which means when the motor is off the resistance is greatly reduced and it feels more like pedaling a regular bike.
The compact hub motor is so small most people will not even know it’s there until you fly by them on a hill!
