Hi, does anyone have a pashley with child seats for sale, i have limited funds and will travel, if not anyone have any ideas on how i could fix two child seats to a tricycle, i can not ride a normal bike due to a bad back, i am desperate to get out of the house with the kids, 2 can ride bikes but the other two one is only 2.5 and the other nearly 5 but has autism, any ideas would be great, wondered if i could make a double seat for the back !!! well my other half could try any ideas many thanks
