Reading closer at the bottom of the M2600 page:
Carrying Capacity: up to 500 lb. depending upon upgrades. Standard version 275 lbs**
**Notes about Carrying Capacities: While other companies put unfounded inflated weight capacity figures based upon no facts, we at Worksman Cycles actually put weight capacities far less than the true capabilities of the cycles, as we take into consideration not only what the cycle will be able to hold, but what is a safe operational weight. Heavier riders (over 275 lbs) should order the bike with drum brake upgrade as well as upgraded tires and tubes. Contact Worksman if you need assistance with configuring the bike that is right for you. We are available at cycles@worksman.com or by phone weekdays 9-5 EST at 800 962 BIKE. Worksman Industrial Bicycles are simply more durable than other brands and have a 100+ year track record to prove it.
If your primary concern is warranteed durability for 385lb, Worksman is what you want.
