Re­cum­bent bike changes into a trike

The Witness - Wheels - - BIKING -

PAS­SION­ATE cy­clist and me­chan­i­cal en­gi­neer Marc le Borgne said he spent many nights thinking how to over­come the chal­lenges of dis­com­fort on tra­di­tional bikes and the low vis­i­bil­ity of re­cum­bent bikes.

The Kervelo bike-trike combo is the Swede’s an­swer and Le Borgne is now rais­ing funds for the bike on Kick­starter.

The Kervelo bike is a di­rect front-wheel drive bi­cy­cle with 18speed gears in the front hub.

The di­rect drive bi­cy­cle re­moves the chain and pro­vides great com­fort, it is ef­fi­cient to ride and very sim­ple to main­tain, a ve­hi­cle that pi­o­neer bik­ers would cer­tainly love, he ex­plains.

As with the £1 999 (R43 000) Ba­bel bike in a roll cage, launched last year by Crispen Sin­clair, the semi-re­cum­bent po­si­tion lifts the cy­clist higher than most car seats and en­ables more ef­fi­cient use of leg power.

Le Borgne is sell­ing the Kervelo ei­ther as a bi­cy­cle or a tilt­ing trike with a 40-litre in­su­lated bag be­tween the rear wheels. To change be­tween bike and trike mode, the rear axles sim­ply slides off the cen­tral frame.

Le Borgne wants 25 000 Swedish kro­ner — about R46 929 — for the trike, but he said this project will go ahead only if peo­ple pledge at least R750 000 on Kick­starter. — WR.
