The Weslo Pro CrossWalk 7.8 offers a host of features for a compact, budget model including the Soft-Cell Plus™ Cushioning, which helps reduce impact on joint by up to 22%, a power incline, quick speed controls, heart rate sensors built in to the handlebars, a folding design, and a workout fan.
The 2.5 hp treadmill motor is peak horsepower not continuous horsepower (chp), so it likely delivers about 1.25 chp which isn’t a strong motor for a walker, and especially not for a runner.
Kudos to Weslo for posting negative customer treadmill reviews on its own website. If that doesn’t send up a red flag, nothing will. The customer complained that they had accidentally left the treadmill powered on overnight, and the controller burned out.
For a cheap treadmill with a 90-day warranty, this machine is a waste of money. With an MSRP of $599, and usually on sale for as low as $399, the Welso Pro CrossWalk 7.8 is a budget treadmill for the lightweight, casual walker.
The weak motor is too small for flat walking, and yet it is strained even further because of the power incline feature, and a suggested 250-lb user weight limit.
A power incline is unnecessary in a budget machine. If a heavy user is adjusting the incline level up and down while strolling, causing the motor to run at high rpms, a number of issues can occur. You can have belt slippage, unexpected speed surges, or the weak motor will fail all together.
If you must buy a treadmill for under $500, take a look at the Weslo Cadence C72 instead of the Welso Pro CrossWalk 7.8 treadmill.
