BOX Four 8-Speed Wide Single Shift 11-42T eBike Groupset (382% Gear Range) - The BOX Four tier is the perfect choice for riders who just want less fuss! You're fond of Prime 9, but know 8 is enough, and surely 11-42T is plenty of range for an 8-speed cassette. The derailleur still has the Limited Slip clutch and now arrives with a more compact cage. The 8-speed chain is built for abuse, although it's sophisticated enough to have its own wide/narrow chainring. Push through fewer gears with a no-nonsense shifter.

Avid BB5 Front Disc Brake Kit (pair) - This kit includes everything you need to convert your trike's brake system to the BB5 disc brake system. Perfect for an upgrade on a KMX, or any homebuilds.

SunLite Locking Brake Lever Set - These locks act as parking brakes and replace having to use parking straps. Forget worrying about your trike rolling away, especially with two locking brakes instead of just one.
