I am a soon to be international student with in belfast on a budget. I have weak legs. I cannot afford a trike. Hence, i decide to buy the Hoptown 20" folding bike which cost £129.99 at decathlon and a pair of adult stabilisers on amazon which said to fit 20"-26" adult bike. However, I cannot be 100% sure that they are compatible as I cannot find anyone that pair them together online. If they do fit, should I buy extension bolts? Please help if anyone has experience on this.
