I've had a coupla noises coming from the NEO Bike Smart over the past year or so. One was easy and required changing the stock belt. The other was difficult to diagnose.
It was a fairly subtle clunking noise that would only occur at lower wattage, and mostly after the bike warmed up. It can be identified by back pedaling and making the same noise.
The solution was to dissemble the idler pully (bearings and sleeve) and use Locktite threadlock on ALL the parts. MAKE SURE THE SLEEVE POSITION IS IN THE CORRECT ORIENTATION AND LOCATION BEFORE LOCKTITE SETS. Wait a few hours before reinstalling.
When I get time, I plan to make a metal pully assembly to replace the cheezy plastic one. There's a lot of pressure on this idler pully.
There's nothing fun about riding a trainer, but when you have to ride one, this trainer is the best!
