Atera makes towbar racks, and its product here is the most thoroughly documented item in this entire catalog.
Where it appears here
The Strada Sport 3, a three-bike towbar rack.
What it is genuinely good at
Publishing everything. Total load 66.9 kg. Per bike 30 kg for bikes one to three, 17 kg for a fourth on the extension rail. Frame diameters 2.5 to 8 cm. Maximum tire width 2.4 inches.
Every other rack in this catalog leaves you to work something out. Atera lets you establish before ordering whether three specific bikes will fit.
Equipment. Wheel trays with rim protection, padded gripping arms, anti-theft protection and rim retaining straps, fully preassembled.
Where it is ordinary
Nothing in the specification. It is a heavy, expensive, three-bike rack, and those are the honest constraints rather than faults.
What to know before buying
The maximum tire width of 2.4 inches is worth checking against modern mountain bikes — plenty run 2.5 or 2.6 inch tires, which will not sit in the trays.
And the arithmetic that governs every rack: your towball’s nose weight, from the towbar plate and vehicle handbook, minus the rack’s own weight.
