This 16 inch mini chain drive folding bike is our most economical 16" wheel bike. It's the identical to the  miniB except it uses a Sturmey Archer 8sp hub & a stainless steel chain instead of a belt system. It is super compact to fit in the trunk of a vehicle or check in luggage, so it is perfect for traveling. The 8 speed Sturmey Archer internal hub provides a wide gear range, which allows this bike to ride like a bigger wheel model. The internal hub doesn’t have any external gears so it is completely maintenance free. Adjusting is super quick and easy, just line up the marks on the hub while in 4th gear, and the shifting will be perfect.

It is super lightweight because the light aluminum frame and small frame size. You will really fall in love with the idea of having one size fits all frames and a bombproof rear hub and shifter. Wait! You will also love to have a rack, rear fender, and kickstand that are now included for free.

The V brakes are smooth and stop the bike fast. Overall, this mini chain drive bike is really small, light and maintenance-free, but rides just like a big bike. This is the ideal bike for a boat, RV, rail and airport travel. You will be so impressed with this cool little bike.

    Mini is Great!

    Posted by Kent From Oregon on Sep 4th 2017

    We purchased a mini back in 2008, and it is great. It has held up very well, and has needed nothing but a bit of cleaning and lube and air. It is super comfortable, stable, and the gear ratios are well matched to our needs (we have the 8sp Sturmey Archer). We chose the green. Very cool looking. We recommend it 100% and Jan has been super fast in his communications always. Thanks, Downtube!
