Made in the United Kingdom (UK).
As a self employed architect and a single parent of two homeschooled kids, I had to take a break from my work during Lockdown 3.0. My keiser bike has been my lifeline in these tough times, keeping me fit and happy while the kids are busy with their studies or when itβs too cold to go outside.
I came up with the idea of making my own keiser Bluetooth converters after seeing how many compalints there were for Keizerβs attempt. (I never bothered with the official Keiser M converter - it had too many issues and was way overpriced - Β£130 in the UK!)
I started with 10, then 20, then 50, then 100β¦ and I might make some more if there is demand - Letβs see how it goesβ¦ Enjoy your ride π΄πΌββοΈπ΄πΌ
What does K2pi mean? Itβs just a short way of saying βKeiser to Piβ (as In raspberry pi computer which I use for every converter).
