The Dolomit It reacts before you have to.

● Perfect for riders who seek power, control, and endurance in one bike.
● For those who love steep climbs, long trails, and rough terrain.
● For adventurers who don’t want to choose between everyday rides and adrenaline.
● For purists who value robust engineering and precise handling.
First measure your inseam. If the measurement is within the green bar, the model fits you.
Take a book and stand with your back to the wall. Clamp the book between your legs. Pull it into your crotch, as if sitting on a saddle. Hold the book parallel to the floor along the wall behind you. Make a line on the wall behind you/top edge of the book. Now measure the distance to the floor. Please take the measurements with your shoes on.
If you choose a bike with a top tube, make sure that the height of the top tube is equal to or less than your inseam (see picture).
(measure the height of the top tube at the point where you are standing in the bike)

A 48-volt system delivers higher power and stronger acceleration, especially noticeable on steep climbs. While many manufacturers avoid it for cost reasons, Deruiz uses 48 V as standard across most models — for better control, efficiency, and riding enjoyment.
The Dolomit uses many standardized components, making small adjustments (e.g. grips, saddle, or handlebar) easy to do through your local bike shop. Please note: Modifications to major components (e.g. motor, electronics, or frame) may void the warranty.
After each off-road ride, clean your bike with a damp cloth or soft brush.<br> Avoid using high-pressure cleaners to protect the motor, battery, and bearings.<br> Regularly check tire pressure, chain tension, and brake pads — it’s the best way to keep your Dolomit performing at its peak.
