Customer review

Seif's Brompton

Say hello to Seif Abdelsalaam from London! He finds his Brompton A-Line very convenient so he converted it to electric with Swytch Folding Kit. Now he can easily overcome any hill. What's more, with our compact kit, he can still use the folding feature of his bike. His four-legged companion Lila enjoys Swytch Kit rides and we're sure you would too!
