I actually bike to work also, but just got this under desk bike and am really liking it. Don't feel like its distance calculator is super accurate, but supposedly I biked 30 miles yesterday. Much better than nothing either way!
Did have to tighten the bolts on my desk chair and lube it to get it to stop squeaking though
It's a DeskCycle 2 - Got it used on ebay and would definitely recommend depending on budget (it cost a bit). The display came with an optional desk mount which is nice. Things seems well thought out and it actually has a heavy flywheel. Manual says it never needs serviced. I was gonna do a walking desk treadmill but I heard some of the people downstairs in our office complaining about how loud they are. I've also heard treadmills make it harder to type but this bike doesn't affect me. AND also I didn't want to have to have a pair of walking shoes at work (my bike commuting shoes aren't great for walking). But I would wager that walking could be a healthier passive working activity than biking (just because I'm still sitting down while I bike and still feel like I need to stand up every hour or so)
That just means they didn't spend extra effort to make it serviceable because they want you to buy a new one sooner. Figure out how to service it anyway.
It has regular screws and is completely disassemble..able..
I've had mine apart just to search out the source of a noticeable noise when I pedaled. Turns out one of the belts had a defect, and it was within the return period so I had them replace it. New one hums along with much less noise.
