{"product_id":"brompton-c-line-12-speed-folding-bike-2026","title":"Brompton C Line 12 Speed Folding Bike 2025","description":"2025 Brompton C Line 12 Speed folding bike. Purchased in Sept 2025 from SJS Cycles but sadly not now used, it’s done about 300 miles. \u003cbr\u003eBeautiful as new condition in unmarked Brompton Racing Green colour-way.  Due to living in Dorset (hills!) it was fitted with the 39 tooth chainring (£38 fitted by SJS from new) down from the 50 tooth std which is too high for hills. This gives you the ability to easily climb hills and does not interfere with cruising or high speeds (this modification is recommended by seasoned owners). \u003cbr\u003eThe bike also comes with a Brompton Roller Frame rear carrier (£135 new) extender seat post (£17) and also includes a brand new Pump (and fittings) and a spare rear mudguard if you ever decide remove the rear carrier.     Note! I also have a Brompton Metro Messenger 25L bag, as new, with frame that will come with the bike if the full price is met.\u003cbr\u003e\u003cbr\u003eNo silly offers you will be ignored\u003cbr\u003e\u003cbr\u003ePayment - Bank Transfer preferred \u003cbr\u003e\u003cbr\u003eNo Couriers    \/    I will NOT post\u003cbr\u003e\u003cbr\u003eCollection in person (or could meet train at Bournemouth)\u003cbr\u003e\u003cbr\u003eNo test rides without prior payment","brand":"Brompton","offers":[{"title":"Default Title","offer_id":64756850459001,"sku":null,"price":1150.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0962\/9640\/3321\/files\/s-l1600_81901ad3-ba0f-4b80-a58d-be2bf72b3201.jpg?v=1790868043","url":"https:\/\/www.foldingbikes4u.co.uk\/products\/brompton-c-line-12-speed-folding-bike-2026","provider":"Folding Bikes 4U","version":"1.0","type":"link"}
