Where to rent a tandem bike in Gauteng?

[I FLY]

Now that we are back in Johannesburg we thought we would ride the 94.7 on a tandem.

 

Anyone know where we can rent one for a few months? The tandem we had previously was a medium /small but my partner was too cramped in the stoker seat.

 

We are not fussed whether it's a road or MTB version.
