I'm trailing this buggy behind a Bafang powered Lynskey 29er to take my 4 year old daughter to the Montessori school here in Gainesville, Florida. There's no road between my house on Millhopper road and the school on the 39th Ave and so our wild ride takes us on a 2.5 mile cut-through, which incorporates a relatively rough 3/4 mile off road segment. It's been raining almost every day here in August and September and so the trail is washed out, very muddy at times, with some standing water too. There's a gnarly steep and eroded hill, and tricky going up. Our daily commute provides a vigorous real-life test of all the Cub's capabilities. The quality and durability of the Cub are excellent, We haven't lost any nuts and bolts up to now, unlike the Weehoo Wego that we previously owned. Overall, I am pleased with the Cub, and I think there is no better buggy out there for serious daily utilitarian useage. However, some features could be improved.
I've swapped out the 1.5" slick tires that came with the Cub for 2.25" tires which we run at low pressure to improve the shock/vibration damping.
(1) The bottom part of the Cub is a durable, plastic basin with integrated wheel fenders. This is great for protecting your passenger from rocks, branches and other road/trail debris that gets kicked up.
(2) The buggy has a primitive spring suspension which helps a little bit at absorbing shocks.
(3) The flap system is a bottom flap held by elastomer ties and a zippered cover. It does a good job at keeping out the water and mud. A better design than any of the other buggies for rainy conditions?
(4) The seating back can be unbuckled which converts the Cub into a nice big utility trailer for carrying your chainsaw, loppers ad machete or other tools.
(1) The wheels are not independently suspended and there is no damping (like a mountain bike shock would have) so the suspension has limited effectiveness. You definitely can't go too fast over rough terrain without giving your kid a concussion. Need to keep too slow speeds less than 5mph. Have you seen the leaf suspension system on the Thule buggies? I am wondering if it isn't more effective than the Burley spring suspension system.
(2) the sun visor was obviously not field-tested. It doesn't stay in one place! After it kept falling down, I removed it and threw it away after only a few rides. It was a nuisance.
(3) A more secure sealing mechanism between the top cover and bottom flap should be devised. The only thing keeping out the nasty mud kicked up by your rear wheel or the road/trail is a 2 inch overlap between the flaps. But there is no positive seal between the flaps, just a passive overlap. Some snaps, velcro or a zipper across the bottom front should be added. The overlap system has been working so far and my daughter hasn't gotten wet or dirty but it doesn't seem very reliable. We haven't been caught-out in an intense rain storm, only light rain conditions.
(4) The elastomer coupling between the buggy trailer arm and the bike bracket is too rigid. I have seen pictures where the buggy is overturned when the bike is laid down on its side. I avoid doing this because it does seem to be a lot of strain on the coupling and I don't have confidence that the coupling won't be damaged. I like the sp[ring coupling mechanism on the Weehoo WeGo buggy a lot better than the Burley system.
(5) The large storage pockets in the cabin are divided by stitching into useable smaller pockets.
(6) There is no mechanism for keeping the shoulder straps in place across the chest like in standard car seats. There is only a buckle down by the waist. The harness is very convenient to use but I think it needs the upper clasp to secure the harness up high on the chest for better safety.
(7) The buggy is on the heavy side, at 37 lbs according to the manufacturer's spec. Other 2 person buggies are a much lighter - closer to 25 lbs. The weight DOES make a difference!
