Review on ROCKBROS Bike Trainer Stand: Magnetic, Foldable Indoor Exercise Bicycle Training Stand with Adjustable Resistance - Ideal for Mountain and Road Bikes by Carlos Reyes

Pros: 1) Installation was easy 2) Very stable with front block and quick release skewer with handle sold separately 3) came folded but fully assembled Cons: 1) The instructions included were for a different product (pulley NOT magnetic trainer) . ) 2 ) Random screw in the box (I couldn't find where the screw is but the product is very stable - see above) 3) The 1-5 level resistance setting is not intuitive. I adjusted the haptics as described on the Amazon page, but this did not result in any noticeable change in resistance. Maybe the manual explains how to set the resistance, but I didn't get the correct manual. 4) You get less cost compared to machines with comparable prices. Others included a quick-change bar with a handle and/or front block. I believe that both had a significant impact on stability. Note. There was a $10 coupon at the time of my purchase which I then used to purchase the separate $13 purchase of the front block and quick release grip pack. Again, this makes a HUGE difference in stability. I hesitated to pedal until the second purchase. Neutral: 1) I'm a beginner, so for my current needs, using my bike's gears to pull is enough. 2) Hum due to tire-to-roller contact. I've read that an exercise splint can fix this. Overall, this product is sufficient for my current beginner needs. But there are similarly priced products that include a front block, quick release rod with handle and/or rocker arm. I would rate it a 3.5 due to its lower price compared to competitors, lack of included accessories and missing/incorrect installation instructions.
