I’d love to have a motor on my Orange Crush but it would have to weigh absolutely nothing because the bike just wouldn’t be fun after adding the extra weight. Motor+battery+stronger frame must be minimum ~6kg so 50% heavier?
That Commencal up there looks really nice but at 20.6kg for a small frame, it weighs basically the same as my Orbea Rise so I can’t see the point. A Levo SL would knock a couple of KG off that weight and be a whole load more fun and be far more usable off road.
Admittedly it’s cheap but spec wise, everything is fairly low. I guess there’s a lot of weight to be saved by ditching the basic coil fork. Could go XT drivetrain and save a load of weight over the linkglide. Some new wheels would save load more and then some carbon bars etc but then you’ve spent enough money to just buy a Rise/Levo/EXe or whatever else is about these days in the lightweight category.
Thinking about wheels, you wouldn’t want to go too light on the wheels because you’re going to need something fairly stout on the rear so may e not as much woeght saved after all.
I dont think you’d ever get it down to a weight where the fun factor of a silly hardtail kicked in.
