Two are fitted to road bikes, one to a "fixie" and one on a tandem. On the fixie, Strava shows the cadence chart as closely matching speed as one would expect so no problems there. If you lose connection intermittently during a ride when there has been no previous problem change the battery. Two of mine started doing this, and within a week the battery was completely dead. Spare batteries and tie wraps are supplied (you have to cut the tie when changing a battery). The need to use a new tie every time you change a battery would be my only gripe. ### ⭐⭐⭐ 3.0 out of 5 stars great in the dry, not great in the prolonged wet *by M***E on Reviewed in the United Kingdom on 2 August 2018* After about 5 hours of being completely soaking wet it stopped reporting correctly.It does work great in the dry, and the data is really useful. It worked for a number of hours in the wet, but eventually it couldn't cope any more, and I had to remove it.3 stars is a fair rating ### ⭐ 1.0 out of 5 stars Don't waste your money *by S***N on Reviewed in the United Kingdom on 9 June 2018* Absolute garbage, save your money and buy something that costs a bit more cos this thing doesn't even work and you'll have to buy the more expensive one anyway. Also it takes ages to arrive from China. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/57322503-somesun-bicycle-speed-cadence-sensor-bluetooth-smart-wireless-ant-cycling](https://www.desertcart.jp/products/57322503-somesun-bicycle-speed-cadence-sensor-bluetooth-smart-wireless-ant-cycling) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-08*
