The ProForm 590 SPX Indoor Cycle combines a Belt-Drive System with Felt-Resistance Tension adjustments for a smooth operation. It has a heavy 48.5-pound flywheel and an innovative braking system for quick starts and stops.
This 112-lb bike offers a fully adjustable saddle (fore/aft, up/down), as well adjustable non-slip handlebars (fore/aft, up/down), and pedals with toe straps to secure your feet. It is compatible with a Polar® wireless chest strap (not included) for heart rate monitoring during the workout, plus a handy water bottle holder and transport wheels.
Reviews on the ProForm 590 SPX note that it has a durable commercial steel frame and is protected by a 5-year frame warranty and 1-year parts and labor warranty. The seat is not all that comfortable, but it is a well-designed and attractive cycling bike that will give you hours of tough workouts.
The ProForm 590 SPX Indoor Bike is listed at $999 at the ProForm website but we’ve seen it around the web for as low as $499 to $599! At that price, it makes a lot of sense.
This belt-drive model is an upgrade on the cheaper chain-drive 490 SPX, but other than that, the frame and components are exactly the same. You will find that belt-drive bikes are very quiet and are virtually maintenance-free, while chain bikes are noisy, and will require frequent oiling on the chain.
You will pay a little more for a belt-drive bike, but it is worth it. If you don’t pay more than $599 for the ProForm 590 SPX Indoor Cycle, then you’ve got yourself a good deal.
