First post, we're new to trials having just bought my 9 yr old son an Oset 20r (35kg). I was going to buy the witter detachable flange tow bar along with the trusted DC bike rack. However the reviews on the detachable flanged tow bar do not fill me with any confidence. Then for my local tow bar installer refuse to fit one, it seems to be the sideways movement on the detachable that is the issue. Any advice from people with experience before i purchase one please? (That's if they ever come back in stock).
