Rohloff Wide Range Internal Gears

Technically, the Rohloff is the boss internal gear setup - 14 speeds and 500% gear ratio, incredible service life - it checks all the boxes.

Technically, the Rohloff is the boss internal gear setup - 14 speeds and 500% gear ratio, incredible service life - it checks all the boxes.

Having all the advantages of internal gears - and with the option of using either a chain drive or belt drive - the Rohloff takes thing to another level with an astounding 500% gear ratio and 14 different gears, and a high efficiency of 95-98%, it is just as good as modern derailleur gears.

Fully protected Rohloff gears are sealed in an aluminium hub shell, making it resilient against dirt, mud, sand, grit, dust, snow and rain. - so maintenance is minimal (cable adjustments), and a minimum of service life 60,000 miles!  Service interval every 3000 miles, which is  an easy oil change. If something more serious happens to your hub, you will have to send it to your nearest service center. Paired with a Gates belt drive you should not have any troubles for quite a long time. 

While the advantages are many, there are limitations. For starters this is a premium upgrade - expect to add at least $1200 to the cost of the bike. It is also heavier. But hey if you want to have it all, the eBikes motor does the hard work of pushing the weight around. 

The electronic Rohloff E-14 gear (standard on all Riese & Müller 2019+) links the mechanical Rohloff Speedhub 14-speed gear hub to the eShift function of the Bosch E-Bike system – an electronic gear shift activation unit. The drive and gear communicate with each other and synchronise the gear-shifting process to make it as light, precise and efficient as possible. An ergonomic switch with two buttons replaces the twist shift grip and gear cables. You can now shift gear in less than 200 ms – currently the fastest gear shift on the market. And that’s with a 526% gear ratio. Multi-shift mode simultaneously shifts 3 gears in a single sequence, while the auto-downshift function automatically returns the gear to your individually selected starting gear when the bike comes to a standstill.
