Hi all,
Long(tail) story, but I'm about to replace my Cube Longtail Hybrid 725 Family after about a year and 2,000 km. Mine is the higher-spec version with the Gates belt and Enviolo hub. I paid around €4,800 and, even now, it seems difficult to beat in terms of components for the money.
I've really enjoyed the bike. I don't mind the relatively high centre of gravity from the 26"/26" wheels and I like that, without the kids, it feels quite like a normal bike. My main complaints are the kickstand, which failed quite early, and the lack of a proper weather enclosure for the kids, which is fairly important in Ireland. I use it for a roughly 4 km school run and then a 12 km commute to work, each way.
I'm 6'1" / 186 cm and currently 105 kg / 231 lb. My kids are 5.5 and 3.5 and are both around 21 kg / 46 lb, so we're 147 kg / 324 lb combined, with 42 kg / 93 lb on the rear rack. My weight should hopefully be heading towards 100 kg rather than upwards, but the kids obviously aren't going to cooperate! Assuming roughly 2.5 kg / 5.5 lb growth each per year, they'll add around 5 kg / 11 lb combined each year.
My initial plan was simply to buy the new Cube Longtail Hybrid Family Deluxe 800, due around December. It addresses some of my issues with a redesigned kickstand, gets the new Bosch Cargo Line motor with up to 120 Nm, an 800 Wh battery and retains the Gates/Enviolo setup. At around €5,100 it looks like exceptional value. I was prepared to fabricate a weather enclosure myself.
However, I've now looked properly at Cube's load tables and that's giving me pause. The bike has a 200 kg maximum system weight including the bike, a 100 kg rider limit, and the rear carrier can apparently only be loaded with 40 kg from above (plus 10 kg per side). The Family bike itself is around 40.7 kg. That means we're effectively already outside the manufacturer's limits today, before the kids get any bigger. It seems bizarre to me that a longtail specifically marketed for carrying children has a 40 kg upper rack limit – two reasonably sized 4–6 year olds can already exceed it.
Question 1: How seriously should I treat these limits in the real world? I'm obviously not suggesting putting 300 kg on a 200 kg bike, but are these conservative certification/component limits, or would you genuinely avoid routinely running a bike 5–10% above its rated system/rack weight? Has anyone here encountered frame, wheel, rack or braking issues from doing so?
Question 2: What alternatives should I be looking at for a relatively big rider carrying two growing kids?
The most obvious one I've found is the Yuba Spicy Curry / Spicy Curry+. The new version states a 250 kg / 550 lb hauling capacity, with a 120 kg / 265 lb maximum rider, and is designed specifically around carrying multiple passengers. It also has a proper factory weather enclosure and the 26" front / 20" rear arrangement should lower the kids' centre of gravity.
My reservations are fit – I've seen at least one 6'1" owner say the Spicy Curry felt slightly small – and giving up the Gates/Enviolo drivetrain for Shimano CUES/derailleur. The Curry also has a 500 Wh Bosch battery rather than the 800 Wh on the Cube. I've also started looking at the Gazelle Cabby C380, which is interesting because it offers a 55 cm frame, Gates/Enviolo Heavy Duty, up to 800 Wh, 26"/24" wheels and an 80 kg rear rack.
I'd be particularly interested in hearing from larger riders carrying two older children, rather than just comparing spec sheets. I'm trying to buy something that will comfortably do this job for another 4–5 years.
Thanks!
