I’ve no idea. Sorry. You could contact customer service for both and ask, they would certainly advise.
I do know (from bitter experience!!) they are hard to get hold of and go for a premium secondhand. So you won’t lose much.
I think... you may perhaps be best off going with a Followme Tandem... especially as you talk about a busier junction etc. I’m useless at linking. Sorry. But google Followme Tandem and see what you think.
Again. Pricey. But. Has much more longevity as it’ll take all wheel sizes up to and including a 20”.
It fits through your rear axle and attaches to the child’s front axle. You are essentially towing them, but they can pedal (and it’s clear when they are peddling 😂). It’s really easy to unhitch them so they can ride independently. The Followme then folds away and attaches to your seat post so both of you can ride unattached. It’s ideal for longer rides where a younger child might tire, so hitch up and tow. Likewise to get them up a steep or long hill. Also if you have any road sections where you want to be in control of them. You can also ride your own bike with theirs attached, without them on it. So it’s great if you do a school run and there’s nowhere for them to leave their bike in the day. It is a very well engineered, robust, high quality bit of kit. Again. Expensive. But also sell very well secondhand. I got mine secondhand for £10 less than new 😱 But I wanted immediately and there was a months wait new.
There are similar bits of kit. The trail gator which looks like a broom handle that you attach on to your bike and theirs to tow. I was concerned about the stories of it being hard to fit and working loose. Then several reports of child bike being at an angle. Another of the child coming loose on a descent. I understand the trail angel is similar.
There’s also something called a weeride. It’s basically a wheel with a saddle and bars that attaches to the adult bike. The child can’t ride it independently though. I also read similar issues to the trail gator in it being difficult to attach and maintain an upright position, it tends to slip to an angle.
I find the Followme incredible. It handles extremely well. We use it for mountain biking, not, really gnarly stuff but fairly rugged. I’ve also used it up and down mountains (on the road). It performs well round hairpins at speed! It just feels very secure and safe.
