I've learnt the secret - noise is directly proportional to the speed you're going at - so for structured work, gear down and let ERG take care of pushing the watts up. I can wacth tv at very moderate volumes if I climb something like Stelvio - different game entirely if I ride a flat / descending route. For route based work I am on Rouvy, so can pick the hillier stuff, so again lower gears, same watts. Afraid if you're on virtual races or Zwift though, not too much you can do. Any of the day, it's the power output that really reflects the work done.
You're not capable (in case you were wondering) This is a great deal - and it is still on!
Been using one of these for Zwift for year and a half, great Zwift trainer, does everything you need from a smart trainer and is far more accurate than wheel on trainers too. At £500 it’s an absolute steal - this is a good quality mid-range direct drive smart trainer and they were in super high demand during lockdown. Only spend more if you are capable of putting out >1400 watts on a sprint..!
Direto is a magnetic trainer. Different trainers suit different users. Fluid trainers tend to be marginally quieter but are typically wheel on designs and dont like high wattage outputs. Direct drive trainers can take 1000W+ sprints but some , particularly those with stepper motors, dont like rapid changes of power and are heavy and bulky if you have to put them away each time. This deal will fit some but not all users but is a very good price in the current market even if the model is a couple of years old now.
Tacx did it with the Bushido - it wasnt popular. Mostly because the amount of power generated was exceptionally small. Most people are working at sub 300W so power available for reuse isnt actually that much when you take out system losses. if you fancy doing a bit of soldering there is this https://www.instructables.com/Best-DIY-Bike-Trainer-Generator/
