As a long-time electric cargo bike user, one of the most crucial upgrades I made was finding the perfect hydraulic suspension fork. With a total load capacity of 450 lbs (including the bike, myself, and cargo), I needed a fork that could handle the weight, provide stability, and ensure a smooth ride across varying terrains. After testing several options and talking to fellow cargo bikers, I’ve rounded up my top recommendations for hydraulic forks that excel under heavy loads.

Why I Recommend It:
The RST Cargo Fork is purpose-built for electric cargo bikes. I’ve been using this fork on my bike for six months now, hauling everything from groceries to gear for family trips. It has reinforced stanchions and a heavy-duty crown that gives me peace of mind even when the bike is fully loaded.
What I Love:
- It feels rock-solid under load, with zero wobble even when cornering.
- The suspension does an excellent job absorbing bumps, keeping the ride comfortable.
