I started using Zwift a couple of months ago with my spin bike. Initially, I paired it with a Wahoo speed and cadence sensor. It wasn’t ideal. The power readings were capped at 400w, which I could easily reach, and it was clearly inaccurate.
Then I discovered the HR2VP app, which estimates power from your heart rate. It worked reasonably well on flatter routes. However, I ran into an issue when I tried a mountain climb. My heart rate went up, and the climb was incredibly challenging, which was great. But then, on the descent, I recovered well. When I got back to flat ground and started pedaling again, my avatar was moving very slowly. Why? Because my heart rate, which would usually be around 130bpm on the flats, was now only 105bpm. The app assumed I wasn’t working hard.
It was frustrating. I’d already ridden 38km of a 70km route and was really enjoying the challenge, but this issue just deflated my motivation.
So, why am I sharing this?
I’ve just ordered a Wahoo Kickr Core. I’ve realized that I want to use Zwift long term, and everyone was right – a dedicated trainer significantly enhances the Zwift experience. My initial hesitation was the cost. Spending £600+ on a trainer, on top of the bike, felt like a big commitment just to “test the Zwift waters.”
I would definitely recommend trying the HR2VP app, especially if you already have a spin bike and heart rate monitor. It’s only around £2.50 per month. Jump on Zwift, try some flat rides and a mountain climb. See if you want to commit to this hobby. HR2VP might even be sufficient for your needs. For me, I’ve realized I want – and need – the full, immersive Zwift experience that a smart trainer offers.
