Revonte ONE: How Its E-Bike Drive System Combines a Motor and Stepless Transmission

Revonte ONE combines electric assistance and a transmission in one e-bike drive unit, with automatic stepless gearing or indexed shifting. Current bike availability and service support are unverified.

Revonte ONE is an integrated e-bike drive system, not just a motor: its drive unit combines electric assistance with a transmission that can change ratios continuously or shift through indexed steps. Revonte’s published descriptions explain how the system is intended to work, but they do not establish whether it, compatible bikes, or service support are currently available.

What is Revonte ONE?

Revonte’s 2019 product announcement described ONE as a package comprising a drive unit, controller, battery and app, with battery power developed in collaboration with BMZ. That integrated approach differs from treating the motor as a standalone component: the drive system is designed to work as a set of related hardware and controls.

Revonte’s 2021 explanation describes a transmission built into the drive unit. The company says a planetary gear set takes the place of the conventional front-and-rear-sprocket arrangement used for changing bicycle gears. These are the manufacturer’s descriptions, not findings from an independent teardown or comparative ride test.

How does its stepless transmission work?

In Revonte’s account, the planetary gear set has a ring gear that is free to rotate. The company says this arrangement allows the transmission to vary its ratio continuously, rather than limiting the rider to a fixed set of gear steps. Revonte also describes two electric motors in the drive unit: one for control of the transmission and one for assistance.

At the rear, the system is described as driving a simplified single-speed setup. Revonte presents both a chain and a belt as possible drive options; the single-speed rear arrangement is distinct from the transmission’s ability to vary the ratio inside the drive unit.

Can it shift automatically, or can the rider change gears?

Revonte material describes two ways to operate the gearing. Automatic stepless operation lets the system vary the ratio continuously, while indexed shifting gives the rider stepped gear changes. The available material does not establish that either mode is faster, more efficient or more reliable than the other.

Mode or choice What it means
Automatic stepless gearing The system varies the transmission ratio continuously, according to Revonte’s description.
Indexed shifting The rider uses discrete gear steps rather than continuous ratio changes.
Rear drive Revonte describes a single-speed rear drivetrain, with a chain or belt as options.

What specifications did Revonte publish?

Revonte’s 2020 material listed the following figures. They are historical vendor-published specifications, not independently verified current production specifications.

Item Figure in Revonte’s 2020 publication
Peak power 1.5 kW
Nominal power 250 W
Gear range 416% at 60 rpm
Drive-unit weight 4.7 kg
Battery 36 V, 635 Wh, 3.98 kg

Those figures alone do not establish real-world range, efficiency, durability, road-legal classification or present-day production status. For example, battery capacity is not a range estimate: actual distance depends on factors the published capacity figure does not specify.

Has a bicycle with Revonte ONE been shown?

Yes. In a 2023 announcement, Revonte described a Pässilä titanium eMTB prototype using ONE and specified maximum continuous assistance power of 250 W for that prototype. A prototype demonstrates an application of the system; it does not prove that a production bicycle is currently for sale.

Can you buy Revonte ONE or a bike using it today?

Current retail availability, compatible bicycle models and service support are not established by the cited announcements. Revonte’s 2020 material discussed an early wave of bicycle-maker partners, and its 2023 announcement documented the Pässilä prototype, but neither confirms which complete bikes are currently sold or where owners can obtain parts and service. The system is presented as an OEM-integrated component, and the available information does not establish a direct consumer purchase route.
