Light and responsive

The Jimi is a capable and agile climber, weighing from just 9.9kg thanks to its aluminium frame, carbon fork and careful component choices.

Low step-over mountain bike

Low step over

Mounting and dismounting is easy with the Jimi’s low stepover frame design. It can be even easier if you add a dropper post. Originally designed solely to help you get lower in the technical sections we have found they are also perfect for riders who find setting off and stopping a challenge. A dropper post allows you to prepare to set off in the saddle with both feet flat on the ground and then raise the saddle once you are riding. You can then lower it again as you prepare to stop – or for the technical stuff!

Versatile riding position and light action controls

Sit more upright or get down low. The Jimi’s 17 degree handlebar stem provides a wide range of handlebar adjustment to suit your riding position. Light action Grip Shift gear changing allows you to use the strength of your whole hand to easily change gear whilst short reach hydraulic disc brakes are easy to operate with limited hand movement and guarantee consistent, powerful braking in all weather conditions.

Easy-Tyre-Change rims

Getting a puncture is never fun. Getting a puncture and not being able to fix it because you can’t remove the tyre is even worse. To combat this, we’ve developed a unique rim bed that makes tyre fitting and removal a cinch.

Carbon fibre front end

The Jimi’s equipped with an exclusive thru-axle carbon fibre fork that features the comfort, precision and lightweight associated with carbon fibre and the benefits of accessory mounts. For full versatility you can fit “Anything Cage” type luggage holders, full mudguards and even a crown mounted light to Jimi’s fork. Perfect when heading out into the wilderness.

Low Q-factor mountain bike

Islabikes size specific cranks and low Q-factor

The Jimi has dedicated crank lengths for each frame size, as short as 165mm for the small model. This seemingly small difference reduces the range your hip and knees have to bend when riding, ensures your muscles are operating in their most effective range and you are more comfortable in the saddle due to the reduced movement at the crotch. The distance between your feet when pedalling has a significant impact on both your comfort and pedalling efficiency. Our unique narrow Q-factor cranks are specifically designed to bring feet closer together and optimise your pedalling.

Remarkably low gearing

Low gearing can be the difference between making it up that challenging steep climb and walking. Jimi’s 11-40t, 8 speed wide ratio cassette and 26t single front chainring provides super-low gearing to ride those climbs.
