Focus Jam 2
First there was hot and then there was sizzling. Then from no battery to one, then one battery to two batteries, Focus have ramped up matters with e-mtb. The new Jam bikes have powerful Shimano Steps motors, new FOLD rear suspension kinematics which are digressive then progressive to give sensitivity then support, plus that all-important Tailored Energy Concept which ultimately means take one battery or two.
It works like this. After switching on the super neat power button on the top tube which then kicks the fully integrated 378Wh battery into life the rider has a choice of either fitting a water bottle and spares or bolting on an additional 378Wh battery for longer rides therefore keeping the weight down for something shorter and sharper or having capacity for a big old day out. The downtube mounts double as both. Cute kids at Focus.
FOLD (Focus Optimized Linkage Design) is a multi link with two rockers giving the aforementioned dual phase kinematic, plus keeping the weight down due to a one piece rear swingarm set up. As a result of FOLD and STEPS the Focus crew were able to keep short chainstays, some pretty good reach numbers and a relatively slack head angle.
The Jam comes on three specifications, three with 2.8” plus tyres and three with 29” wheels. They come with Shimano and Rockshox suspension, a mix of Sram and Shimano drivetrain. In short we cannot wait to ride this bike.
