adjustable magnetic resistance

The main function of the magnetic resistance is to provide quick, easy and reliable changes to the resistance level. Magnetic resistance is generated by single or multiple metal disks through a magnetic field providing infinite levels of resistance. The closer the magnet is to the flywheel, the greater the pedal resistance will be. Unlike bikes with traditional tension systems, bikes with magnetic resistance never come in contact with the flywheel, resulting in a silent, stable and virtually low maintenance experience.


4-Way Adjustable seat

The comfortable seat can be easily adjusted for height and proximity to handlebars. Easily adjust back and forth and/or up / down) for convenience and stability so your workout can remain comfortable when riding for long periods of time. Adjustable seating allows for multiple people in your household to use the equipment comfortably and efficiently. Having the correct seating adjustment is important to assure you won’t fall while giving it your all.

Great bike

Easy to assemble. I unpacked the bike outside and brought it inside one piece at a time. The main portion, frame+flywheel, was very heavy, but I managed on my own. I’ve gotten in 20+ rides so far. I use the Peloton app for $12.99/month. My IPad fits in the holder perfectly and I use wireless headphones. The included monitor is great for cadence. The heart monitor doesn’t seem accurate to me and I no longer use it. There are nice multiple positions to hold on the handlebars and water bottle holders as well. I weigh 210 and the bike is extremely stable, even when out of the saddle and climbing. For me, the only con with the bike is there is no way to tell what the resistance setting is at any time. It is very easy to adjust the resistance, but I wish there was some type of numeral setting. I just give it a few twists of the knob when I need more or less resistance. The resistance can easily be set from nothing to extremely hard. I would buy this bike again and can recommend it to someone looking for a great workout. It feels like a commercial unit that is very well built.

My Pandemic Bike

This thing is a tank.... extremely solid, and operates smoothly and quietly. The instructions had a couple of things that could be improved.... the bracket that holds the performance monitor looks completely different in the instructions, which caused some confusion, and the portability wheels can be installed on the front, or the back. The instructions do not offer that as an option as you are building it, but mention it later in the operating section. Beyond that.... the build quality is fantastic. The performance monitor is not backlit, and doesn't show WATS.... but that was known prior to purchase, and I'm OK with that. The knob for adjusting resistance allows very slight changes in resistance, so making large changes in resistance requires quite a few turns of the knob, but I've decided I like the ability to make slight, smaller changes. I look forward to using the bike every day.

We were missing all of our cycle classes due to the quarantine; We were not having it! This company had the bike that we wanted and we got it within a week with a discounted price! It is perfect! Now we can do all of our cycle workouts from the home. It is a much better bike than the one we were using at LA Fitness! Kudos !

Asuna 6100 totally worth it.

First, I consider myself a runner and ride a bike to complement my overall fitness level, take some stress of the joints from all the running I do and a change of pace. I've had the bike now two months and it has been worth it. The bike is sturdy, the clips hold my feet with enough play for easy of pedaling and get in and out of them. The bike easily handles my 160 lb body with no shaking. I also like the fact the bike is quite, the magnetic wheel is definitely the way to go. The water bottles and tablet holders are in the right place. The reason I give the bike 4 starts instead of 5 is due to the Display monitor, hard to see if the room is dark, doesn't measure resistance and it just looks and feels cheap; I would have paid a bit more for a sturdier meter (can you make an upgrade). Finally it was easy to assemble but I would suggest two people when handling the box.

Update to my review of October 16th

After little bit more then two months I finally got the parts to fix my brand new bike which was standing around collecting dust. I also got a little refund (10%) from Sunny after asking for it. The repair itself was easy assuming you are not heavy-handed. The bike is great. It works fine and offers so many ways to adjust it to your personal needs, body size and strength. The resistance can be adjusted very accurately and offers enough power to challenge even well trained riders. After my previous back and forth journey with customer service I can conclude that Sunny offers good products but definitely has to work on their customer relations.
