FITS ALL KEISER M3/M3i/M3iLite/M5 COMPUTERS (NOT NEW STUDIO COMPUTER) : PHONE and SMALL TABLET STAND/HOLDER.
FOR EUROPEAN SALES PLEASE NOTE EU IMPORT TAX WILL BE PAYABLE BY BUYER ON DELIVERY.
I created this design out of necessity, as the limited space on the Keiser media tray was insufficient for both my tablet and phone. The built-in computer became redundant for the apps I frequently use, and the latest upgrade of the Keiser computer was underwhelming. My goal was to design a solution that complements the bikeβs aesthetics without adding unnecessary bulk or attachments to its frame.
This product is crafted to enhance your spinning experience by integrating with the βKeiser M series appβ. It displays all the metrics available on the bikeβs computer screen, and crucially, it shows the FTP% or Power zones necessary for apps like βKeiser - the rideβ, which guides you through various intensity levels with color-coded graphics. Alternatively, it can simply keep your phone within reach while you exercise.
The stand is compatible with a range of devices, tailored specifically for my iPhone 11 Pro but also accommodating majority of typical sized phones on market. Larger devices such as the iPad mini can be secured with an additional band. However, it may not be suitable for larger iPads or Pros due to their size and weight over the handlebars.
Designed for convenience, the stand easily attaches to the top of the standard Keiser M3/M3i/m5 computer, ensuring the computer screen remains visible when not using a device. It features three adjustable positions for the top phone support band to fit the size of your phone or tablet.
Please be aware that this item is 3D printed, a method that allows for its existence and affordability, as traditional manufacturing would likely be cost-prohibitive for such niche products.
Injection moulding is great for making millions of simple items, but itβs very expensive for small quantities of complicated items. So, please consider that the surface finish is different to injection moulded parts. Since parts are built up one layer at a time, they do have distinct features. LAYER LINES - a fine grain can be seen, STEPS - on sloping surfaces the surface wonβt be completely smooth. NOZZLE LINES - on flat surfaces slight lines will be visible where each pass of the nozzle joins.
Each item takes hours to print & is one of a kind and individually finished. Item is made of PLA, a durable and waterproof plastic that wonβt break down if you sweat on it. However, it is sensitive to high temperatures (above 100 degrees Fahrenheit), so if your bike is exposed to high heat, consider removing the item when the bike is not in use.
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).
