Range THUNDRA
Season 2021

Access a whole new world of adventure with our electrically-assisted trail bike, Thundra.

It uses a specific version of our fully butted, XC race influenced Xtralite alloy frame housing an internal battery that provides 630Wh of range to the proven E7000 STEPS motor (you can add even more range with a frame mounted 360Wh extender cell!) Big rotor Shimano brakes and SRAM SX Eagle 12-speed drivetrain give super reliable stop and go control. RockShox Recon 120mm air sprung fork and either 29 x 2.6in or 27.5 x 2.8 Maxxis Rekon rubber flow and float you over the roughest trails. And of course it wouldn’t be a Mondraker if it didn’t have our power dialled Forward Geometry to make every meter the most fun possible.
