Surface 604 Shred

The 2020 Surface 604 Shred is a value-priced hardtail cross country style electric mountain bike with 9-speed SRAM 11-34 tooth cassette, plus-sized tires, a higher top speed of 28 mph, super-responsive torque + cadence sensing bottom bracket, quiet motor, and trigger throttle that overrides assist for full power. Available in two frame sizes medium-large or small-medium for improved fit and comfort, optional 14 amp hour battery upgrade to extend range, optional rear rack, optional fenders, optional suspension seat post, and the bike is pre-wired for an optional rear light. Good sized 180mm hydraulic disc brakes with motor inhibitors on both levers, rear-rack bosses, bright integrated headlight, an adjustable-length kickstand, and decent 100mm spring suspension fork with preload and lockout adjust. More expensive than the prior-year model, stand-over height has been lowered and the paint is updated.
