JLL Sonic 1 Air Bike, Exercise Bike for Home Use, Stationary Bike with Air Resistance, Assault Bike with App Compatibility, Fan Bike 130kg Max User Weight

This is a great product and so far has been perfect - bought during the 2020/21 winter lockdown for some home exercise. The assembly was relatively straightforward and once put together the bike is very sturdy. The trip computer is quite basic but does give the important data. At 6ft 1, I would say I am at the limit for user height on the bike. All in all a very good experience for some high intensity cardio.

there's a good amount of pros and cons with this bike:pros -Not excessively heavy, has transport wheelsFairly quiet due to it's final belt driveEasy to useNice flex through the frame during use, also you seems to dial up the effort as you put in the effort, the Airdyne 8 as a comparative is either off or full effort!Small footprintConsPrice increased from £450 b4 lockdown.The seat reach adjustment WILL wear and the seat won't stay in place, had to drill holes straight through both sections and slot a bolt in to hold.As above, tablet holder is in wrong position.Final drive from the pedals to the fan is a belt, however there is a chain connecting the pedals inside that you'll struggle to reach to oil.Squeak - thought this was going to drive me mad! hunted a squeak that I swore was coming from the seat post or fly wheel just to eventually track it down to the pulley that the belt sits on take power from the pedals to the flywheel. somehow the belt slips to side and rubs against the edge of the pulley, you have to remove the cover and very carefully ease it back over whilst slowly turning the pedals. Don't bother putting the cover back on as this will need doing every few weeks or when there's a change in the barometer (even after adjusting the tension on the adjusters).Eye bolt holding the pedal drive arm to the bottom of the arm drive handles sheared off suddenly, eventually had to take the matter into my own hands and source a replacement bolt pair.No handle on rear to actually pick up the back and move the bike around.As a £450 bike I'd buy every time, possibly as a £500, £550 or even £600 bike - as an £850 bike... no!! Let's just say there's different branded versions of this bike out there that have had the majority of these issues resolved by component redesigns, rhymes with Rimal Strength!UPDATE - Second lot of eye bolts holding the pedal to arm handles have seared off abruptly, there's obviously a design fault that overly stresses at these fixings.

The bike arrived in a damaged box and a couple of parts needed replacing. This was quickly done by the company with little delay and was still in a useable state. Most of the bike was already built which I was happy about as the instructions to construct it had it not been would have taken me a while to complete. I’m 6’3 and this is probably the max user height as the seat is at its top setting. Having said that it is sturdy and looks good. There was some squeaking but lubricant comes with the product and did the job. I have used the bike almost every other day since purchase and not had to re apply anymore lubricant yet. I have never used an air bike before so can make no comparison but having researched a lot before making this purchase it seems like value for money. The foot rest pegs need quite some tension to prevent them undoing when using. If I could have 1 thing changed it would be that the iPad holder was incorporated in some other way. It can only be held portrait as if put landscape the arms hit the pad and you can not see the integrated bike computer when watching anything on the iPad. I will no doubt resort to getting a tv on the wall in the spare room I have it in.

Pedal came off after three sessions on the bike. The pedal is a screw in but the thread stripped itself which is why it came out and now won’t screw back in. Lot of money for the pedal to break so quickly after 3 uses.

It arrived 2 packages on different days (annoying) Easy to assemble with a basic practical ability. A bit noisy to begin with they supply lube oil but I used WD40 much easier. Overall fairly quiet. The electronic consul is basic but I use Iconsul+ free app on my Android Phone , you can only use a heart monitor with the app even if says you can you cant. I use CooSpo Heart Rate Armband Monitor works with Iconsul+had this bike for about a month my wife and I use it everyday still good I have used a Schwinn at a gym it compares well except for electronics. Hope that helps any one considering it, I bought it on price good value I think.
