I’ve ridden for 5hours with an under 2 in a weeride top-tube mounted childseat, it’s a much better experience for wee ones than a rear seat as they’re actually involved and you interact with each other the entire ride. I have used rear seats and trailers a lot too and they just don’t compare, rear seats are the worst of all as they mess up the bikes handling and you can’t even see the wee one for this reason I personally never liked leaving kids in rear seats for more than about 10-15mins without properly stopping to make sure they were still happy but with the weeride you can actually both enjoy the ride together, even semi-technical XC riding can be done with them easily, steep chutes/climbs, small drops, roots etc. are all a breeze as all the extra weight’s centred too. if you’ve got a spare £65 I guarantee you won’t regret spending it on one.
