Slim E-road bike: Can you tell that the Rose Reveal Plus has a motor inside?

This article was first published on 2 October 2025 and has now been updated.

The Rose Reveal Plus is the first electrified road bike in the Bocholt-based company's range. The inexpensive bike is only recognisable as an e-bike on closer inspection and is the spitting image of the eponymous marathon bike. The reason for this is the compact motor, which sits in the rear wheel hub to save space and is powered by a comparatively small battery. During our test rides in the foothills of the Alps, the Mahle X20 scored with its power, especially at low pedalling power, the drive pushes remarkably in turbo mode and makes climbs easier.

Rose Reveal Plus 105: Compact, unobtrusive motor

There are a total of three riding modes, which are set using the control unit on the top tube. A remote control for the round handlebars is available as an option. The visual proximity to the Reveal means that the comfortable character of the motorised clone comes as no surprise. Thanks to the long head tube, the handlebar sits high above the front wheel and puts the rider in a decidedly upright position. Overall, the frame geometry with extended wheelbase and flat steering angle is designed for high directional stability.

Low total weight and roadworthy

Thanks to the low total weight of less than twelve kilograms by e-bike standards, the Reveal Plus can be ridden at a relatively fast pace even without motor assistance. The 32-millimetre tyres are sufficient for the actual purpose of use on asphalt roads, but the official tyre clearance (33 millimetres) is a little tight for longer off-road rides.

At a current price of 2999 euros - the price was reduced by another 500 euros from 3499 shortly after our test - the Reveal Plus 105 the cheapest candidate of all the test bikes. Rose offers a further equipment variant, for an extra 1500 euros you get carbon instead of aluminium wheels, a fully integrated cockpit instead of a handlebar-stem combination and the electronic Ultegra groupset. The Rose Reveal Plus Ultegra Di2 is for example available here.
