Beto bike seat rack alternative

[dave]

Hi all

Apologies if this is not the right place to post this.

I have just bought a Beto Deluxe baby seat which my two year old son
loves. The rack supplied is for 700c wheeels but my bike is a 26 inch
wheel mountain bike. There are brackets supplied which make the rack
fit but it looks like a botch job.

Does anybody know if this bike seat is compatible with other racks? Or
alternatively if there is a Beto rack specifically for 26 inch wheels?

Thanks

Dave
