I have a Toyota Prius (hatchback) 20212. Despite trawling I cannot find a rack which would take the weight of 2 e-bikes. This Prius does not have provision for a tow bar so that's out.Chatting with Wiggle they were of the same opinion. Has anyone found one?
Two things you need to do:-
1) What is the allowed roof load on your car? Many cars have 50Kilos or less as a design max.
2) Even with the battery removed, 2 of almost any e-bike could exceed the load possibly allowed.
3) I personally found over 10 years ago (2004), that placing two normal bikes on a special bike roof rack, was very tiring. A small slip and paint would easily get damaged.
After one holiday, I sold it!!
Both my caravan and a small trailer I own, have better methods of carrying bike(s), without the need to place/hold them over my head....but both need a Tow Hitch!
If you are very tall, very strong and relatively young, (and new dents & scratches are unimportant) then it could be OK.
The car handbook should help further with regard to load. But roof loads are often FAR lower than you might think....especially on small cars.
On some cars, the high load, combined maybe with holiday luggage and the family, can affect the car's general stability...
Roof racks also present a extra high wind resistance, increasing fuel consumption, often dramatically.
Many bikes fall off for some reason, and the owner may even be held responsible for damage to dozens of following vehicles, or for causing an accident. Especially if people are injured or worse.....
I do think that a car that cannot take a tow hitch, it is wise to find such things out before purchase.
To me personally, a car without a tow hitch is as good as useless.
Do think this through carefully, and make sure that the bikes are really strongly mounted and can come loose maybe, but never, ever fall off.
Perhaps sending the bikes to your destination via say a rail or lorry delivery service, though not cheap, may still be a "cheaper" alternative in the long run....
