There is a thread about this around here somewhere. We liked it and used it a lot. DS is too big for it now though. It wa good as they are between your arms and you can see them and talk to them. The downside is that your leg don't rise as straight as with a normal bike because you put them a bit to the side to fit the seat in. I still liked it though.
We have a Bo-bike (similar to Weeride) and DD2 is still riding in it. She absolutely loves it and it is great from the perspective that you don't have to turn around to see them, you can talk to them and they don't have to lean out to see (and unbalance the bike). The other bonus is you can ride with a backpacj on or have a pack rack on the back of your bike. We often have DD1 attached at the back with a trailgator so the rear mounts weren't an option.
DH takes DS for rides all the time with the wee-ride. They both love it, DH says it feels much safer having him in front. DS even falls asleep on big rides, there is a little headrest and he looks pretty comfy.
I asked the same question in another thread a while back, and we bought one. It's fantastic. DD loves it, it's easy to ride with her on it. She's 2 1/2 and showing no signs of being too big for it. Go for it!
