Upway’s Hands-On Review of the Riese & Müller Roadster Mixte Vario HS!
What makes the Roadster Mixte Vario HS ready for the city?
You can’t just shove a Class 3 drive unit in a frame and call it a day. A commuter bike needs to be fast, comfortable, durable, and low-maintenance. Riese & Müller accomplished all of that and more with the technical build of the Roadster Mixte Vario HS.
- Frame: Riese & Müller used lightweight and durable aluminum to make the frame of the Roadster Mixte Vario HS, giving it the ideal properties needed for the city. It includes a step-through design, keeping the rider more stable when mounting and dismounting the bike, especially when carrying cargo. This design also makes it more comfortable to stand at a red light.
- Drivetrain: The shifting mechanism of the Roadster Mixte Vario HS is a unique one. Its Enviolo Heavy Duty rear hub offers stepless shifting rather than fixed gears, so riders can adjust their cadence at any time. This system pairs with a belt drive, making the bike very easy to operate and nearly silent.
- Integration: To fully prepare the Riese & Müller Mixte Vario HS for the city, it comes equipped with full fenders and a rear rack. It also has the option for a front carrier and frame lock. The bike is integrated with a Supernova M99 Mini Pro-45 headlight, keeping you visible and safe as you ride at night or in poor weather conditions.
What are the electronic highlights of the Mixte Vario HS?
HS stands for “high speed,” and the drive unit behind the Riese & Müller Roadster Mixte Vario HS is a big reason for that designation. It is a Class 3 electric bike, so make sure that it is legal wherever you plan to ride. This e-Bike is a powerful and integrated piece of technology in the body of a city bike.
- Drive Unit: The driving force behind the speed of the Riese & Müller Mixte Vario HS is its Bosch Performance Line Speed mid-drive motor. This Class 3 system can put out 85 Nm of torque and reach up to 28 mph, making it ideal for longer and faster commuting. It comes with a Bosch PowerTube battery, which adds up to 625 Wh of range. The battery is integrated safely into the downtube.
- Integration:Bosch helps to integrate all their components by making them all compatible with the Bosc ecosystem and app. The motor, battery, and display controls are all found in one spot. The Bosch Purion display keeps track of your stats, status, and component health. Using all Bosch components rather than a mix makes it a cleaner interface for the user.
- Safety: The Riese & Müller Mixte Vario HS is designed to be ridden at high speeds alongside traffic, so it needs to be safe. It comes with a horn and the option for a rear-view mirror. This is unique for e-Bikes, but necessary in this case since it essentially serves as a car replacement. The integrated light also helps keep you safe in low-visibility conditions.

Frequently Asked Questions
Do I need a license to ride the Roadster Mixte Vario?
Why did they use a step-through frame?
There is a misconception that step-through frames are only for people with mobility issues. They are actually great for all urban riders, since you will often be carrying cargo. Swinging your leg over the toptube with extra weight on the bike is not always a good idea. It also makes it easy to stand and relax at a red light.
Where can I buy a Riese & Müller e-Bike?
Riese & Müller is a sought-after brand, but because they pulled out of the US market in July, it is becoming increasingly difficult to buy their new bikes. Upway buys and refurbishes used bikes, meaning we are able to get our hands on Riese & Müller bikes and sell them for a discount.
Key Takeaways
- The Riese & Müller Roadster Mixte Vario HS has serious speed: As the “HS” suggests, this is a high-speed road bike that comes with a powerful motor, so you can get anywhere you want to go in record time.
- Bosch runs the whole system: There is no mixing and matching parts here. Because Riese & Müller chose to use Bosch for all of their electronic integration, it is easier for the user to navigate settings and control their ride.
- Always check local laws: Every state has different electric bike laws, and some towns even have their own. Make sure you check to see if anything is different when you go to ride somewhere new, especially if you are on a Class 3 bike.
