    Perhaps you’ve never heard of HaiBike, a German company that’s been around since the mid-’90s. Even if it’s a few decades younger than big names like Giant, Specialized, and Trek, the company built a mid-drive electric mountain bike that performed every bit as well out on the trail as models from those better-known marques. CR testers found that it had the most modern geometry of any of the bikes tested, which meant that it had stable handling on trails and gravel roads. Power delivery isn’t as smooth on the Hardnine 5.0 as on some of the other big-name mid-drive models we tested, but it also costs several hundred dollars less.
