Lightweight and stiff frame construction
Excellent traction and control on varied terrain
Innovative Asymmetric Integration drivetrain
Slightly heavier than some competitors
Limited DIY tuning potential for suspension

Drop your heels, let go of the brakes and the way it seems to melt serious drops into nothing is truly phenomenal
The Jekyll is one of the fastest and least tiring bikes of this travel that we’ve ever ridden

Great geometry and handling for Enduro riding.
Simple and more user-friendly suspension.

Excellent geometry and kit plus unique shock create a crazy-fast enduro ripper. Buy if you want sorted shape, pert/plush performance with metal wheel toughness
Gemini shock system allows instant switching between super-plush speed or a tighter, more dynamic ride
Long-stretch/slack-head geometry, wide/short cockpit and XL front tyre create a massively confident front end

Weight is pretty chunky for a medium-size £5k bike
Limited DIY tuning potential of the linear-feeling rear shock
