This topic seems to be getting off track..the guy wants advice about a folding bike that will fit in his car and that he can take out for 20 or 30 mile rides..and the occasional 100 mile charity ride..I said a Dahon Speed P8 would be good and a BF Tikit..please do not get a Brompton..great for sticking in your car but hard work for 30 mile bike rides and 100 mile rides...I have a Brompton but would prefer 20 inch folder for anything over a few miles..Had a Tikit also..great ,great little bike..fold size is much bigger than a Brommie but the ride is fabulous...The Dahons that have 16 or 18 speeds would also be a good choice as would the Tern 24 inch wheel bike..already mentioned..
