A full-size fat-tyre bike with front suspension
The DiroDi Voltz combines 26 x 4-inch tyres with a step-over aluminium frame and a suspension fork. This listing follows the existing 500 W rear-hub configuration and 840 Wh removable battery. Its upright controls and broad tyres give it a substantial character, with eight-speed Shimano gearing and hydraulic disc brakes providing familiar mechanical control alongside the electric drive.
Tyre volume and front suspension
The Veetire Co Zig-Zag tyres have a broad four-inch profile and are listed as puncture resistant. A KKE fork provides 100 mm of front travel and a thru-axle front wheel connection. This remains a front-suspension bicycle, with a rigid rear frame; correct tyre pressure and suspension setup both affect how it feels on the route.
Removable frame battery
The 48 V, 17.5 Ah battery stores 840 Wh and can be removed for charging. A Bafang brushless rear-hub motor supplies the drive in the selected 500 W option. The display presents riding information, while the mechanical gear range lets you select a comfortable pedalling cadence independently of the level of assistance.
Brakes and drivetrain detail
The listed Tektro Auriga E-Comp hydraulic brakes use 180 mm rotors. Shimano Altus eight-speed components provide shifting across an 11-34T cassette, with a 42T front chainring. A conventional chain drivetrain means routine cleaning, lubrication and brake checks remain useful parts of ownership even though the bike has electric assistance.
Fit and supplied equipment
A riser handlebar, comfort grips and gel saddle support the intended riding position. Mudguards and a front light are listed, but a rear light and rear rack are not part of the supplied configuration. The tall step-over frame and 85 cm listed standover height make rider fit especially important on this full-size fat-tyre bike.

Choosing your setup
The Voltz is sold in different motor options, and the existing card represents the 500 W version. Check the supplied electrical configuration and intended use when ordering. Allow for the full-size tyres and high top tube when assessing storage and fit. We will confirm colour, accessories and final components before payment; a rear light or carrier is a separate addition.
