            Lightweight e-bike

            Ride and manoeuvre with ease

            Thanks to its aluminium frame, carbon fork and careful component choices, eJoni weighs from just 15kg; riding and manoeuvring is effortless. Furthermore, the eJoni features full wrap mudguards, luggage rack, and integrated lights, for maximum versatility.

            Super low-stepover

            Getting on and off the eJoni is as easy as it gets with its very low stepover frame - as low as 32cm on the XS size. To make life even easier you can add a dropper post, this will allow you to prepare to set off in the saddle with both feet flat on the floor and then raise the saddle once you are riding. You can then lower it again as you prepare to stop – brilliant for junctions.

            How far can I ride with electric assist?

            The typical range is 40 – 50 miles per charge, but this will vary with the amount of electric assistance you use, terrain and surface, your weight, and the temperature. A hilly ride using maximum assistance on a cold winter’s day uses significantly more power than a flat ride in the summer. At 15kg the lightweight eJoni can also be ridden comfortably without assistance.

            Technology you can trust

            The slim and lightweight Mahle X35+, 250Wh battery inside the eJoni's downtube is constructed from cells manufactured by Panasonic. The battery reaches full charge in approximately 3.5 hours from flat using the included fast charger.

            Smart ebike assist MySmartBike app

            A system that works for you

            The eJoni is pre-programmed with three assistance levels to cater for multiple styles of riding. If you would prefer to customise this, it is easy to do with the accompanying MySmartBike app. You can also access additional features such as heart rate based variable assistance, activity tracking and remote support.

            Light-action, comfortable controls and riding position

            The eJonis’ swept back handlebars give an upright, comfortable riding position and put controls at your fingertips. Light action Grip Shift gear changing allows you to use the strength of your whole hand to easily change gear. Short reach hydraulic disc brakes are easy to operate with limited hand movement and guarantee consistent, powerful braking in all weather conditions. The ebike controller is simple and easy to use with vibration and LED feedback.

            Wide ratio gears

            The eJoni’s wide ratio 11-40t cassette provides low enough gears to make the difference between making it up a climb and walking – especially when laden with shopping. Light-action Grip Shift gear changing allows you to use the strength of your whole hand to easily change gear.

            Short reach hydraulic disc brakes are easy to operate with limited hand movement and guarantee consistent braking in all weather conditions.

            Size specific cranks with low Q-factor

            The eJoni has dedicated crank lengths for each frame size; as short as 160mm for the extra small model. This small difference reduces the range your hip and knees have to bend when riding, meaning your muscles are operating in their most effective range and results in more comfort 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 designed to bring your feet closer together.

            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 overcome this we’ve developed a unique rim bed that makes tyre fitting and removal easy.

            Carefully prepared by us

            Islabikes trained mechanics will assemble and adjust your bike prior to dispatch whilst also fitting any accessories. When it arrives with you, following some minor assembly on arrival, your bike will be ready to go. Your bike comes with a set of hex keys for setup on arrival.
