Diamondback Exercise Bikes Buying Guide

Diamondback Fitness was founded as Diamond Back in 1977. Today it’s a part of LifeCore Fitness with headquarters in southern California. The Diamondback brand was first a pioneer in BMX bikes and now makes a wide range of road bikes, indoor bikes and elliptical trainers. Most of the indoor bikes use magnetic resistance but Diamondback also distributes an air bike. This buying guide compares Diamondback exercise bikes in different categories.

Diamondback Magnetic Upright Bikes

Diamondback Fitness makes two upright exercise bikes that use quiet magnetic resistance: the 510Ub and 910 Ub. These steel framed trainers sell for just $699 and $999, respectively. Both exercise bikes have plenty of preset workout programs plus support for entertainment. They are iPod compatible, have USB ports and have foldaway magazine racks. Which is better for your needs? The 510Ub is the best value for shoppers seeking light to moderate resistance. The 910Ub offers a wider range of challenge levels. Diamondback upright magnetic bikes are sold with standard three-year warranties on parts and are best buys at their price points.

Diamondback Upright Airbike

While most stationary bikes today use magnetic resistance, the Assault Airbike uses fan air resistance. This setup allows for infinite resistance levels! The bike wheel is 27″ in diameter and delivers air resistance to match the rider’s force. You can use the bike for everything from gentle rehabilitative cycling to intense cardio training. The Assault Airbike not only fits all skill levels, but also comfortably fits most children and adults. It is unusually durable too; expect it to serve for hundreds of thousands of hours.

This bike earns rave reviews for use by pro sports teams, fine fitness centers, the military and family members of all ability levels. It sells for just $999 and is virtually maintenance-free.

Diamondback Recumbent Bikes for Home Gyms

The two recumbent Diamondback exercise bikes are the 510Sr and 910Sr. These award-winning bikes have sale prices of just $799 and $999, respectively. Each provides good lumbar support and positions the rider for pedaling with minimal stress on the knees and ankles. These bikes also have cooling fans to encourage longer training sessions.

Which recumbent bike is best for you? The Diamondback 510Sr is the better value if only light resistance is desired. The 910Sr is a better choice for more challenge; it has a heavier flywheel and double the number of resistance settings. The 910Sr might also be a better choice if you’re interested in having an expanded workout menu; the 510Sr offers a nice selection of 20 preset workouts but the 910Sr has 35. Both of these recumbent bikes are good values at their regular prices with three-year parts warranties and other buyer protection included.

Diamondback Indoor Cycle Trainers

Diamondback’s two indoor cycle trainers are the 510Ic and 910Ic. Compared with other styles of indoor bikes (upright and recumbent), cycle trainers operate especially like road bikes. Compared with indoor cycle trainers from other brands, Diamondback’s bikes are unusual for including preset workout programs.

How do the bikes compare with each other? The Diamondback 510Ic has a 32-pound flywheel and 14 preset workouts. The 910Ic has a 40-pound drive and 18 preset programs. The bikes sell for just $799 and $999, respectively. Both carry five-year parts warranties for residential use.
