A lightweight backroads e-bike built for the way you ride
The Tui Backroad brings together low weight, a comfortable riding position, and Bosch electric assistance in a titanium e-bike designed for touring, commuting, and recreational riding. Starting at approximately 36 lbs, it delivers a sporty, responsive ride without losing the familiar feel of a regular bicycle.
Whether you are exploring country roads or riding your daily commute, the Tui Backroad puts comfort at the center of its design. An upright position supports long days in the saddle, while low standover clearance makes getting on and off the bike easier. A wide range of wheel and tire sizes lets you choose a setup suited to your riding.
Titanium construction. Responsive ride feel.
A lightweight titanium frame is central to the Tui Backroad’s character. It is designed for riders who want electric assistance without giving up the engaging feel of a conventional bicycle. The result is a titanium e-bike that combines responsive handling with the comfortable position you want for longer rides.
Bosch pedal assist, with a choice of drive units
The standard Bosch Active Line Plus drive unit provides smooth, comfortable pedal assistance up to 20 mph. It is a straightforward choice for recreational rides, touring, and everyday commuting.
For riders who want assistance at higher speeds, the optional Bosch Performance Line Speed upgrade provides pedal assistance up to 28 mph in a Class 3 configuration. The upgrade is available at an additional cost.
SRAM Apex AXS: precise wireless shifting at a great value
The Tui Backroad comes standard with SRAM Apex AXS wireless electronic shifting, delivering precise shifting performance at a great value. It pairs electronic shifting with wireless operation, rounding out a lightweight titanium e-bike built for touring, commuting, and recreational riding.

Semi-Custom for a perfect fit
Tui bikes use set frame sizes, with fit adjustments tailored to the rider. Rather than building a custom frame, we work from your fit requirements and select from the components we keep in stock.
- Fit adjustments: We customize crank length, stem length and angle, spacer stack, saddle width, and handlebar selection based on your fit.
- Accent colors: You can choose colors for the headset, spacers, and seat binder, plus handlebar tape on builds that use it.
- Wheels and tires: We select a wheelset and tires suited to your type of riding. We offer several tire options; contact us for the current selection.
- Frame Color: Frames come in bare titanium with anodized graphics. You can pay extra to have the bike painted any color you want. Please ask us for pricing on a custom paint job.
Frame size is the starting point. These adjustments let us tailor the bike’s contact points to you. After you place your order, we’ll send instructions for submitting your measurements or arranging an in-person bike fit.
