Another contender has emerged in the ebike conversion kit market, with Asus launching the E250G1 Intelligent Bike Booster at the Taipei International Cycle Show.

The device clips onto any conventional bike and uses a friction-drive system to transfer power to the rear wheel, similar to the Livall PikaBoost.

Asus says the device enables you to enjoy up to 51km of range thanks to a removable 159Wh battery.

There are three ride modes: Eco, Normal and Sport, with the latter offering the most grunt at the cost of range.

The system itself is said to weigh in at around 3.8kg and is compatible with bike wheels from 16in to 29in, including 700c.

A swingarm in the device presses down into the tyre to ensure there is slip-free power transfer, and the cadence sensor on the cranks is wireless.

There’s a rear light built into the device, too, which has a braking detection system that alerts other road users when you’re slowing down.

The battery charges via USB-C and takes around two hours to charge fully using a 100W PD charger.

Asus says the device is IPX5 waterproof-rated, and there is an Android and iOS companion app.

I gave the device a quick try in the exhibition hall, and the sensitivity was impressive.

Whether we’ll see the Intelligent Bike Booster make it to the UK market is unknown, but it’s a neat little device.
