The E-14 Solo

The E-14 Solo combines the directness of a mechanical shifter with the speed of electronics — and needs no e-bike. It is made for gravel, touring, city and cargo bikes alike.

Simple and self-contained

No app, no cloud, no registration. Switch it on and ride. A short press shifts one gear — standing still or under load — and holding the button shifts several in a row. That keeps shifting in hand in stop-and-go traffic, on climbs and off-road.

Two control versions

Handlebar	Control unit	For
Flat bar	Rohloff Trigger	city, trekking and cargo bikes
Drop bar	TRP Hywire Brifter	gravel and adventure bikes

Its own power

The E-14 Solo runs on its own battery, independent of the bike’s drive:

• more than 1,000 km per charge,
• charged over USB-C, right on the bike,
• integrated in the frame with internal cabling on factory bikes; mounted externally on the frame when retrofitted.

Compatibility

• Every SPEEDHUB ever made — whatever the year.
• Dropout widths 135–197 mm — up to fat bikes.
• Works with a Gates Carbon Drive belt.

Built to last

It follows Rohloff’s long-life principle: instead of replacing a system, it develops the SPEEDHUB you already have. A good bike stays usable for decades and can still be upgraded — fewer replacement parts, less waste.
