Key findings
- The Riese & Müller Supercharger offers exceptional range and comfort thanks to its robust construction and dual battery.

- This bike is ideal for long commutes and multi-day bike trips.
An indestructible e-bike
When we talk about the Riese & Müller Supercharger, we're not talking about an ordinary electric bike. With its sturdy frame, two integrated batteries, and virtually indestructible build quality, the Supercharger is designed for cyclists who don't want to compromise on range or comfort. It's the SUV of electric bikes.
Advantages: power & comfort
Thanks to DualBattery technology (often 1,000 Wh or even 1,250 Wh), you can travel long distances without worrying about range. Under ideal conditions, a distance of up to 160 km is possible. Riese & Müller is renowned for its German precision, high-end finish, and reliability, and the Supercharger is no exception.
The combination of a suspension fork, wide tires , and a suspension seat post effectively absorbs road irregularities. Equipped with the Bosch Performance Line CX mid-drive motor (85 Nm), the bike always delivers sufficient power, even with heavy luggage or on hilly terrain.
Disadvantages: weight & investment
With two batteries and a solid frame, the bike is understandably heavy, often weighing more than 30 kg. This makes maneuvering without assistance or loading it onto a bike rack more difficult.
Thanks to its long wheelbase, the bike is extremely stable, but less playful and less maneuverable in narrow city centers.
The Supercharger is clearly positioned in the premium segment of the market. And quality comes at a price.
Models and variants
The Supercharger is available in several configurations, tailored to specific uses:
- Touring: equipped with a classic derailleur gear system. Ideal for sporty cyclists looking for maximum efficiency on hilly terrain.

- HS (High Speed): speed pedelec version speed pedelec assistance up to 45 km/h, ideal for long daily commutes.
- GX: Off-road version with a wide choice of transmissions, tires , and a front rack.

Its impressive battery capacity and the option to add extra luggage racks also make it an ideal vacation bike for long cycling trips.
Finally, thanks to its excellent shock absorption and remarkable stability, it offers sufficient comfort for cyclists who want to avoid or alleviate physical problems.
Practical tips for use
No test without useful advice. Although the recommendations below apply to most electric bikes, the Supercharger does not require any special treatment.
- Batteries should not be completely discharged. There is no memory effect (loss of capacity due to incomplete cycles) if you recharge at any time. Batteries offer approximately 800 to 1,000 charge cycles. In winter, store them (or the bike) in a dry place at room temperature.
- Keep the pressure of wide tires below the maximum (3 to 3.7 bar) for optimal comfort and grip, especially in hot weather. Always check the information on the sidewall of tire.
- Keep the system software up to date via the Bosch eBike Connect app. You can also activate additional safety features there.
- Consider maintenance: schedule an initial service after 500 km or after 3 to 5 months to check the bolts and transmission settings.
Supercharger: a legend that lives on
In 2026, with a little luck, it will still be possible to find a Supercharger stock model. However, it has disappeared from the catalog since the 2025 collection.
The spirit of this bike, with its robustness and dual battery, lives on in other Riese & Müller series such as the Superdelite5, the Charger 5, and the Charger 4 GT.
For those who absolutely want a Supercharger, a refurbished model refurbished an excellent alternative. Used prices (starting at €2,600) are significantly more attractive than new prices, which ranged from €6,500 to €9,000.

The Riese & Müller Supercharger is the ultimate long-distance e-bike for those who are willing to invest in top-of-the-line quality. Despite its high price and heavy weight, it offers unmatched range, exceptional comfort, and a particularly safe riding experience.
