Bike test: Islabikes eJoni urban e-bike

The Islabikes eJoni
The electric version of Islabikes’ sit-up-and-beg step-through is ideally suited to riders with less strength or stiffer joints. Dan Joyce test rode it and polled other riders’ opinions

Like the eJimi, the eJoni is the electric version of a bike built for older or less able riders. The step-through frame, upright riding position, low gears, and easy-tyre-change rims remain. A 250W Mahle hub motor adds power for easier pedalling.

This adds weight but not so much that it’s hard to manhandle. At 15.5kg (size M) the eJoni is no heavier than many unpowered city bikes, and light enough to be lifted up a few steps or onto a towbar- mounted bike rack by most owners.

Mounting and dismounting is easy thanks to the low-step aluminium frame. If you needed it to be easier still, you could fit an externally cabled dropper seatpost. The bottom bracket isn’t too high, however, so it’s not hard to get a foot down without a dropper. Pedalling is nicely ergonomic thanks to shorter cranks with a narrower pedal tread.

The digital display on an e-cycle mounted to its handlebars shows shows various data

The 250Wh battery in the down tube isn’t meant to be removed until it needs replacing (after about 15,000 miles, at a cost of £599.99), so you must park the eJoni near a socket for recharging. It should do 30-40 miles per charge. As ever, range is hammered by very steep climbs (I took it up a 25% hill).

Standard fittings include mudguards, a rear rack and high-quality Supernova lights wired to the main battery. You can’t fit bottle cages except to the carbon fork or a stem-top mount (£13). A propstand (£23) is another extra. Get one – and the optional, wireless PulsarOne display (£100) that the test bike came with.


Arguably the pinnacle of the whole, keep-you-riding Islabikes Icons and e-Icons ranges. It’s super easy to mount and dismount, easy to ride and easy to live with. Next time someone says e-bikes are “cheating”, show them this.
