The Rugged Space Saver

The new RadMini 4 now comes with our exclusive 20" x 3.3” Kenda K-Rad multi-terrain tires. With a higher load rating than a standard bike tire, as well new, narrower handlebars for an ergonomic grip, you’ll be more comfortable, for longer, on all your Rad rides.

Don't let the "mini" in its name fool you. Sure, the RadMini can quickly fold when you need some extra room, but this ebike packs quite a punch when you're ready for action and adventure. Power, convenience, and versatility make this rugged space-saver a truly unique addition to any arsenal.

The Rad Battery Pack

With over a decade of designing and building ebikes under our belts, we know that a high-capacity battery like this isn’t something you cheap out on. We designed and built our batteries using genuine Samsung 35E cells, which are some of the most energy-dense and reliable lithium-ion cells on the market today. These cells have allowed us to build an overall better battery, and at only 7.7 lb, it's one of the lightest and most energy-dense packs on any electric bike.

With 750W and 80 Nm of torque at your disposal, this Bafang geared hub motor is what is going to help power you up steep inclines and get you up to top speed quickly from a dead stop, all while remaining quiet and inconspicuous. These kinds of numbers aren't even found on some of the most expensive mid drive systems out there, so prepare to outperform and outclass everyone you see on the road.

Love our Minis!

My husband and I are 60 somethings. We bought 2 Rovers last year. We rode them 600 miles and really enjoyed every minute but felt they were a little too much for us to handle as we are both some what “shortish” “height challenged” so we decided to purchase Minis. They are a much better fit for us! Love both Rover and Minis just more comfortable on the smaller Minis!

Comfy, Fun, Controls handy, Pull my 55-lb dog!

Comfy handlebar grips. Nice being able to sit straight "in the saddle" due a shorter seat-handlebar distance and adjustable seat & handlebar heights. Easier to pedal than my mountain bike even without using assist. All controls in just the right places. Easily tow my 55-lb Goldendoodle dog in a 25-lb trailer using 0-3 assist and 3rd gear. Wife and I can't wait to ride our minis every time temp is above about 42 degrees. Well-built & sturdy bike. Wish I could add pics to this review. Only "negatives" are bike weight and a little tricky installing/removing the battery without it slipping out of my hands.

RAD Ride

So far, so good. Love the pedal assist. I'm just getting over a broken leg and the power to start from a dead stop is very helpful. Today I went 11 miles with the Bike Club I joined and my battery meter shows fully charged. A few more accessories and I'll be all set.

It feels rejuvenating riding bikes again with my Radmini. I get to work-out while riding a little or a lot, my choice. No hill is too steep anymore.

Clicking

Sent a note last week and no reply yet. Bought two bikes in November and on the full size bike I started experiencing a "click" that I hear and feel with every revolution of the pedal. Any troubleshooting thoughts....and also, any suggested company here in SoCal if I need to take it for servicing/repair??

Bike needs fenders

Fenders should be much cheaper or included on bike. The bikes throw a ton of debris at eyes. Dangerous for eyesight! 90 dollars is too expensive for a part that should be necessity for safety.
