VDO M3.1 WR Wired Bike Computer Odometer with accessories:
• VDO M3.1 WR Computer Head Unit (New battery installed) • Wired Handlebar/Stem Mounting Bracket • Fork-Mounted Speed Sensor (Attached to cable) • Wheel Spoke Magnet
In used condition. Cosmetically it is in very good condition. Screen has only a few very minor marks which aren't really visible unless you look for them.
Please note that this item was removed from a used bike therefore has not been tested on a bike. I have inserted a brand-new battery, and the head unit works as intended—the screen is crisp, and it smoothly scrolls through all initial setup prompts (clock, language, wheel size, etc.). Because I haven't ridden with it, it is sold as-seen without full road-testing. No original packaging or manual included can be found online • Official VDO M3.1 WR English Instruction Manual • VDO M3.1 WR Quick Start Setup Guide

The mounting bracket and speed sensor were attached to the bike with zip-ties which had to be cut to remove them from the bike (as shown). I will throw in some new zip-ties but I'm not sure if I have any black ones in this size to match the original ones so might be a different colour; However you can purchase these from any local DIY store for 'pennies'. The handlebar/Stem Mounting Bracket also had adhesive 'double sided' tape/pad on the underside to fix it in addition to the zip-ties. This is still 'tacky' but you may want to add some fresh double sided tape to prevent it slipping.
