For two years now, the Allgäu-based company has been putting the pedal to the metal when it comes to e-mountainbikes and has with the Ekano (last in BIKE 9/25) has already won several test victories. Despite direct shipping, Propain bikes are not exceptionally cheap. Our Sresh SL CF Bomber test bike is even the most expensive in our comparison test of light E-MTBs around 6000 euros. On the plus side, there is an elaborate full carbon frame, double-sealed bearings and the Pro 10 rear suspension system, which Propain has also integrated into its E-MTBs since the Ekano. Our Sresh SL test bike is its little brother with slightly less suspension travel and is one of the first bikes ever to be equipped with TQ's new HPR 60 whisper motor.
The Sresh SL is one of the few Light E-MTBs to offer a removable battery. The battery is also secured with just one screw, making it particularly easy to remove. Thanks to the configurator concept, you have the choice: would you prefer only 360 watt hours and extra light, or 580 watt hours for more endurance? Both batteries fit in the same down tube. However, the large battery weighs 800 grams more and costs an additional 400 euros. We therefore opted for the cheaper and lighter version for the test.
For the motor itself, Propain relies on the new TQ HPR 60 (tested here) which combines a particularly discreet background noise both uphill and downhill with a now mature performance and sensible torque. A stylish display sits in the top tube. For additional range, there is a range extender in water bottle format.
The configurator also comes into play again with the equipment. However, if you click on all the fine options here, you will quickly end up with 8,000 euros and more. We have therefore made a special selection to maximise value for money. The Marzocchi suspension is rather heavy, but offers good trail performance and many adjustment options and doesn't cost the earth. The same applies to the Sram Eagle 70 transmission. The brakes are Magura's MT5 with short levers, and the test bike rolls on Continental tyres with plenty of puncture protection at the rear and a super-soft rubber compound at the front.
Although the Propain Sresh SL is still brand new, the geometry looks surprisingly conventional. No super-short chainstays, no extremely long reach. With classic values, Propain tends to build on a high feel-good factor and gets the performance out of the good suspension (see below).
We find the central, slightly front-wheel orientated riding position on the Propain to be the ideal compromise between uphill strength and touring suitability. The Sresh SL also shines with plenty of traction. The HPR 60 motor shines with low drive noise, direct engagement and a natural riding feel. Only on really extreme uphills do the motor power and the lack of trail set limits.
The Propain has few weaknesses on the climbs, but we liked the Sresh SL even better on the descents. The Marzocchi suspension proved to be harmonious and sensitive and is pleasantly defined, especially in combination with the Pro 10 rear suspension. The Sresh SL lacks neither comfort nor reserves for full-throttle rides. Despite the rather inexpensive components, this is a real high-end level.
The supposedly conventional geometry gives the Sresh SL an uncomplicated character. The high front with riser handlebars and the sticky front tyre encourage you to attack even on steep terrain, while the 150 millimetres of mid-travel at the rear only becomes a limiting factor late on. Bike parks and enduro trails are no problem for the Sresh SL. The good thing is that the Propain is also fun on less extreme routes and twisty home trails. Although the chainstays are not quite short, the Sresh SL is still easy on the rear wheel and scurries through tight turns without much effort. There are even lighter-footed and more playful light bikes, but the balanced mix of playfulness and downhill qualities is convincing. Unfortunately, our test bike developed an annoying creaking noise after a few rides. Apparently, the single retaining screw for the battery is somewhat vulnerable. However, cleaning and tightening improved the situation.
With a modern and uncomplicated geometry and excellent suspension, the new Propain Sresh SL has hardly any weaknesses, even in an affordable configuration. The quiet TQ motor fits perfectly into the concept. Test victory! Extensive selection options in terms of equipment, battery and wheel size are available on top in the configurator. - Adrian Kaether, Editor Test & Technology
