Marin Alcatraz 1 26w 2025 - Jump Bike
At home boosting your local 6-pack, ripping up the pump track, or hitting the local skate park the Alcatraz has what you need to take care of business.
The Series 3 aluminum frame is built for the hard knocks and is stiff enough for lightning-fast acceleration and tough enough for the heavy hits. Short stays keep manuals easy and ambidextrous cable routing means you can run your brake on the left or right of the bars. There’s a suspension-corrected CrMo fork, front and rear Tektro disc brakes, Vee Tire rubber and plenty of bombproof Marin components. Best of all, it’s available in two frame sizes, regular and long.
Occasionally, without notice, manufacturers change product design and/or specifications.

Jump Bike Size guide
Jump bikes are designed and intended for Dirt jumps, street and skatepark riding. Not for riding any distance.
They primarily use a 26” wheel with the frame only available in one size, to suit riders taller than 4’5” or 137cm.
Some manufacturers offer a long or short length bike. Riders over 5’10” or 178cm will prefer the longer option.
