Convert any standard bike into a cargo bike. The Temper Cargo Fork replaces your front fork with a 20" wheel and a built-in cargo platform — turning a regular bike into a Cycle Truck capable of carrying real loads.

Made in-house in Santa Cruz. The strongest cargo bike fork available, with an adjustable axle-to-crown length that lets you dial in steering feel and preserve the geometry of your original bike.

  • Adjustable rack angle — pivots to stay level regardless of your bike's headtube angle
  • Two-position flip chip dropouts — change axle position to fine-tune fork length
  • Huge tire clearance — fits 20×1.75" up to 20×3+" tires
  • E-bike ready — motor cable routing and battery mounting points built in
  • Modular dropouts — QR, bolt-on, 12mm, or 15mm thru-axle compatible

Pair with our front hub e-bike kit to build an electric Cycle Truck. Free shipping in the contiguous US.

Cargo Bikes For Everyone

Install this fork on your bike to massively increase your cargo capabilities. Cargo forks turn a normal bike into a Cycle Truck — with a smaller 20" front wheel and a lower, more stable loading platform built to handle real loads.

Our fork is designed with the flexibility to fit a wide range of bikes and use cases. Here's what sets it apart:

  • Adjustable Rack Angle: The rack pivots to stay level regardless of your bike's headtube angle — unlike typical cargo forks with a fixed rack.
  • Two-Position Flip Chip Dropouts: Open dropouts with included inserts let you choose two axle positions, effectively increasing axle-to-crown length by +15mm in the lower position.
  • Huge Tire Clearance: Fits 3"+ tires with the axle in the upper position — ideal for maximum stability under heavy loads in rough conditions.
  • Variable Effective Fork Length: Combine the two axle positions with compatible tire sizes from 20×1.75" up to 20×3+" to dial in your front-end geometry and preserve the feel of your original bike.
  • Modular Dropouts: Stock dropouts fit QR and bolt-on axles. The modular design can also be swapped for 12mm or 15mm thru-axle hubs.
  • Cargo Mounting Points: Four sets of 3-pack mounting points — one on each fork leg and two on the underside of the rack — for water bottles, cargo cages, mini panniers, or extra batteries.
  • E-Bike Ready: Designed with electrification in mind: extra-thick dropouts, motor cable routing, and dedicated battery mounting points. Pair it with our 20" Front Hub E-Bike Kit to build an electric cargo bike.
