Random bike frame assignment | 1.86 [March 2025]

Using Samsung Galaxy S23 Zwift update 1.86. Just purchased SWorks Tarmac SL8 and been late joining big spin. i choose the new SWorks Tarmac SL8 first time. Then each time i joined after i was on different bike. First it was specialized atheos, then zwift aero, tron, retro cruiser from last year etc. I stopped mid ride after late join. re-select Tarmac. once route is complete i get put on another different bike!
anyone else experiencing this?

update: rebooted phone and tried again. Went to garage, selected the new tarmac bike exited garage.. went to another event, Herd social ride.. joined.. i was placed on zwift steel bike! So I stopped and discarded the ride, went back to garage, selected a different the bike, this time the focus izalco max. Exited garage and went back into garage.. i was not on the bike i selected! i was on the cervelo aspero!! I repeated this insanity selecting different bikes each time and ended up NOT on the bike selected.. Did this 5-6 times. eventually it seems my selection finally stuck with me..

Hi @Fred_Williams_KBRC_C, thank you for raising this issue. I’m not seeing many other reports of this, but I’ve flagged it up at HQ for more investigation. I may update the title of this thread as we find out more.

It is normal to see your bike change if you join or leave an event with an assigned bike, or if you have a time trial bike equipped and you join an event that does not allow TT bikes. It doesn’t seem like any of these exceptions were the case for you, so we’re looking into this as a new issue.

Thank you for your response.

Yep, I am used to the normal “automatic event bike swap” behavior. You are correct, what i experienced was not the same.

tested again this morning and the issue was not present.

Thanks

I’m seeing this on Windows app. I go to the garage, pick a bike, start the ride and I’m on the wrong bike. This is annoying because I’m upgrading the wrong bike.

i just tried windows and can confirm same issue exists

I’m seeing this on MacOS so it’s not only Windows

I’m experiencing the same issue and it’s really frustrating. Today, I rode 90 km to upgrade my Tarmac SL8, but the ride was credited to the Aethos instead. My wife had a similar problem the other day, where her ride was credited to a different bike. We were both using Windows PC.

Doesn’t seem to be affecting me on M4 Pro Mac Mini running almost the latest MacOS 15.3 - I’ve been changing between a few different TT bikes and SL8.

I’ve mostly been doing free rides.

I didn’t see it with multiple rides on the Windows machine, but I fired up the Mac today to test something else and ran into the bug. I chose a bike from garage, started a ride, and was placed on a different but recently used bike. I replicated it a few times and the bike was different each time but always one that I had used previously.

I also had this - MacBook Pro. Joining Big Spin having selected Specialized Venge before joining pen. What I see is me on a Zwift carbon bike but I asked someone to click on me and tell me what they saw me as riding and they said the Venge (and I did get Km credit) but then when I went through the finish line banner I was then on a TT bike! Crazy!
