Have you slacked off the external pinch bolt that lies between the headset and the handlebar stem hinge?

There are 2 different systems, you will need to post pics so we can help you. Removing bolts is not necessary and may in fact cause some hassles. See if you can put it back.

If iit is the sort of bolt that came with bikes traditionally, then slacking it off and giving it a tap with a hammer will loosen the wedge internally. More modern bikes come with a set of pinch bolts. Pics please! ☺

It's a house brand of SportsDirect, which is a bit like a UK version of Dicks Sporting Goods. The Evolve looks to be a Dahon clone Dunlop | Dunlop Evolve 16 inch Folding Bike | Road and City Bikes

Yep, a Sports Direct special. Its not a bad bike but that stem is a bit clumsy and mares the fold bigger than it should be. Frame looks well made and very similar to the Dahon Curve.

I this the bike?



If so, loosen the pinch bolt under the hinge above the steerer bearing.

yeah the picture shown is the one.I actually removed the lower bolt but still cant move the handlebars.I wondered if they were on a sort of spline that had to be lifted up and turned but I cant lift them either.I must be thick cos Ive never had a problem with other bikes lol.

As mentioned by cpg, it does resemble the Curve D3, although I see that the top tube appears a little shorter than the Curve which is perhaps emphasized by the slightly more forward tilt to the handlebar stem. Not a whole lot more mind you. If that be the case, then the wheelbase should be a tad shorter as well. Just an observation.

Fold the handlebar stempost. There should be a bolt inside the hinge that must be slackened. This is a downward bolt.

There aren't any others... The clamp must be binding. Try inserting something into the clamp gap and carefully lever it open to break the bind. Don't over-do it.

That screw might be on a tapered nut, when you have slackened the screw off try lightly tapping it downward. If that doesnt work send it back to sports direct because its faulty.

It resembles the way they made the Satori stem raiser : 2 wedges machined to squeeze the portion of the arc of the steerer tube from both sides.

Once the bolt is loose, but still threaded in, while the hex wrench is still in the bolt bang on the wrench with a hammer .. that should break loose the threaded half of the clamp pair.

once its loose you van take it out and tap from the inside out to dislodge the other one the bolt head passes thru.
