I run Ubuntu on a 5510 and I love it. I get between 5 and 7 hours of battery life with it. Using the NVidia card will kill the battery, so be careful and make sure you set up Bumblebee/BBSwitch on Linux (or the NVidia settings on Windows). Otherwise, it's a great machine. I picked up the 32GB model with a 1TB NVMe drive and QHD+ display.
However, it is a bit too large for a bike commuter and I'll be selling it on eBay shortly.
