I recently got delivery of the new smartbike SB 20 and the feedback from DC Rainmaker and GPLama was spot on, pros and cons. In this post i would like to reiterate a few of their points.
I love the ride feel, the ease of dialling in the riding position and I love to have a dedicated indoor training bike. I am really happy with my purchase however everything isn’t perfect though:
My issues so far:
Pairing SB20 with Zwift, the pairing process seems to work but when you start the game Zwift doesn’t recognise that you are pedalling. usually it works after a restart of the Zwift app. But it is annoying that you need to do this almost every time you start to train. I used to train with Wahoo Kickr and I never had that problem. Another “pairing” related problem: at one occasion Zwift recognised the SB20 but in Erg mode but the wattage wasn’t right, it was kept about ~25w too low.
Erg Mode power fluctuations, this have been reported, 3 July, by DC Rainmaker and he believes it can be addressed with a SW update. However it is still a problem, power accuracy seems to be spot on but when in erg mode the power jumps +/- 25-40W, when I keep the same cadence and wattage it shouldn’t have to jump, Stages reported to DCR that it was challenging with the heavy flywheel, that seems odd to me, if that was the case the problem should occur during changes in cadence and resistance not during steady state? average watt during an interval is about right though.
Gears, the SB 20 can be controlled by Stages Link app that will show which gear you are in, SB20 doesn’t have a dedicated display. However the Zwift support team wrote this to me “we do want to recommend refraining from using any other apps along side of Zwift, since doing so may cause inconsistencies within your ride data and the information being transmitted from your equipment to your device.”. When in SIM mode it is neat to be able to see which virtual gear you are in and it would therefore be great to be able to have this displayed in game.I have written to the Zwift dev team. I understand this works with the Wattbike Atom and according to DCR, Stages have given the needed interface information too Zwift so hopefully this will be implemented in a near future.
