Today I installed pinhead locks to my RadExpand 5 seatpost and front wheel. Those were the only parts compatible, but feels justified for the cost of replacements! : r/RadPowerBikes

Anyone have experience with pinhead locks? I bought a replacement key and it doesn't fit! The company does not know how to fix the situation and has rendered the bike unridable. Wheels
