Very nice bike

Recently purchase so I could spin at home. It was really easy to assemble - everything clearly stated in the instructions. The 49 lb flywheel makes the bike extremely sturdy. I have no reservations about climbing, doing jumps etc. very solid state. I do have two issues: I’m fairly short and even with the seat pushed all the way forward I can tell I could use it even more coward. But my biggest disappointment, though certainly not a deal breaker is that the tension isn’t able to be adjusted specifically to a certain level. When adjusting you’re guessing the level you’re at. There aren’t any numbers/levels marked so you end up adjusting a lot to hopefully hit a level that you can only determine by feel. But overall it’s a nice bike and made really well.

Solid Bike and a Great Value

Got this bike a steal of a price on Amazon (~$300). At this price point, we weren't expecting a lot but we were pleasantly surprised. Solid, stable, smooth and quiet. You can feel the difference a 49lb flywheel makes. Setup was pretty easy (there's a great YouTube video). We bought clip-in pedals, a Wahoo cadence monitor and an attachment to mount an iPad. Now, we have a Peloton setup at a fraction of the cost.

Solid Bike

The bike was easy to put together and is very sturdy. The flywheel is quiet. The seat and handlebars are easy to adjust. The wheels in the front make the bike quick to move. Great bike.

LOVE this bike! So glad I didn't spend two thousand extra dollars on the Peloton. Sure, Peloton has a lot of fancy and super cool features - but I get a really great workout on my Sunny - it's paid for; and I'm not forced into paying $39 every month for the subscription to Peloton. For that price - I could join a gym; actually, I could join a gym with spin classes - for less!
