Firmstrong 29" Black Rock Single Speed, Matte Black - Men's Beach Cruiser Bike w/ Heavy Duty Wheel



The Firmstrong Black Rock takes cruising to a new level with 29-inch wheels. Taller riders love the bigger wheels, and others enjoy the advantages of riding the Black Rock. Larger wheels help riders gain momentum and maintain speed, without extra exertion. A great fit for most men from 5ft, 5in to 6ft, 5in tall, it's ideal for cruising and recreational bike riding. The 19-inch length frame is constructed of durable aluminum, with 29-inch aluminum wheels with wide tires roll smooth and easy as well as cushion the bumps as you ride over them freely. The wide, oversized seat completes your comfort with dual springs that help make the ride soft and cushy. Both the seat and the handlebars can be adjusted for height and tilt to ensure maximum comfort. Whenever you need to stop, you simply pedal backwards, easing on the coaster brake. Other features include wide cruiser bike handlebars with synthetic leather grips, waffle tread tires, a guard to protect pant cuffs from getting caught in the chain, and a 350-pound maximum weight capacity. The bike is shipped 80 percent assembled. Firmstrong has been designing high quality, affordable bikes for over 10 years with a focus on blending style and functionality to create a fun, adventurous experience for riders -- not just a mode of transportation.

Great bike with one exception

This bike is just what I'm looking for. It's 29 inch wheels, aluminum frame, coaster brake setup is perfect for racking up the miles while staying comfortable. The exception is the cheap, one piece bottom bracket they used. With that, it rides like a cheap bike. The BB bearings started to go within 2 weeks. I ended up swapping it to a 3 piece crank and a cartridge BB with conversion kit. With the conversion, it rides spectacular. It's disappointing they would cheap out on such an important part.

Xlnt bike.

Just got my Black Rock. It came quickly when ordered. It was easy to assemble. It is a very solid and well built bike. It is pretty fast for a 1 speed cruiser. It is a perfect fit for larger riders.

Great bike, great service

I was amazed at the packaging and shipping of my bike, each individual part was wrapped in padded material and it was in perfect condition. Assembly instructions were easy and was completed in less than an hour. First ride was outstanding although short due to 20mph winds beachside in Florida. Highly recommend.

A nice beach bike but...

I love my Black Rock 29" in general, it rides well. Some parts have started to rust 30 days after taking it out of the box. The bike lives close to the beach and all those parts not made from alum. or ss are starting to show rust. I keep it clean and use a spray on these parts so the rust does not get out of hands but there is no reason why some of these parts are not made from alum. or ss been a "beach bike"

Great customer service
