Can You Lend Us a Bike Rack?

We are doing a house swap with a Spanish family(two adults 8 yr old girl) from 3-16 August. They are keen to take up our suggestion of cycling on the Lea Valley Navigation Canal towpath. We have plenty of bikes. We also have a functioning bike rack. We are happy using it but others staying here have felt it was a bit flimsy and tricky to use. We think its fine for us so dont want to buy another. Do you have one a bit substantial that you could lend us for the fortnight? They'll be driving a Vauxhall Corsa. Thanks.
