Why we chose it

Exceptional tech

After fiddling with all manner of knobs and screws on other spin bikes, we were relieved to encounter the sophisticated, console-equipped DiamondBack 510Ic. If you appreciate the full-service programming and screen quality of gym equipment, you will feel more at home on this spin bike than any other we tested. The 510Ic centralizes resistance adjustments, programming, and performance stats in one slim display — about the size of a credit card reader. (Diamondback’s level-up, the 910Ic, is nearly identical in structure and tech, with slight tweaks to flywheel weight and programming depth that we didn’t find impactful enough to rationalize the $200 upcharge.)

Smooth ride

Our ride experience on the 510Ic was luxuriously smooth and steady. The heavier body of the Diamondback 510Ic means it sits solidly on the floor, holding you secure as you hit higher intensities or stand to pedal. And thanks to the variety of programming, we were confident we could find a workout for any fitness goal.

Points to consider

Reduced adjustability range

When it comes to adjustability, the DiamondBack doesn’t have quite the same extension range as the Bladez. That said, the seat can ratchet up higher, making it a better fit for users with extra long legs. We also appreciated the numbered and lettered adjustment levels on this bike — a Diamondback feature that was sorely missing on most other spin bikes. Rather than have to rediscover your perfect placement every time someone else goes for a ride, you can just remember that your seat sits at “G” and quickly slide it into place.
