folding bicycles
Yes we are aware that there are cheaper electric bikes and or kitts available. But very few systems work as well as the Bionix and these usually require a from the ground up new frame design ( Bosch ) and / or are actually way more expensive than the Bionix. In other words everything else we tested so far is way inferior product than what we offer here.

Please call us with any questions, also we have from time to time a demo bike where you can save some of those hard earned greenbacks
Bionx KIT S 350 DL

This is the kit which works best on all folders. But if you are not mechanical inclined to say the least you should find a capable dealer to do the work for you.

    Tern Verge X

    Tern Verge X frame is the backbone of this wonderful conversion

    We have addded a HD Tern 100 mm fork, with Avid disc brakes and more spokes to accomodate the extra weight and power this bike conversion has.

    I will enjoy riding this bike myself and looking forward for trips together with my girlfriend. Meaning this bike is really not for sale, however, If I can make somebody happy owning such a nice and one of a kind machine, I will heavy hearted let go.
    price is without the trailer and bag, custom double waterbottle holder.

    Bionx 2010

    This is the top of the Line Bionx system. 500 Watts are pushing you up the steepest hills and get you to your destination in a hurry.

    We dont save on anything, you will get the lightest 37 volt battery either as pictured or in the attractive bag, the valuable throttle lever, all cables customized to your specific needs. And probably most important our knowledge to make the electric bike conversion a real success.

    We know that the price asked for a Bionix System invokes a mild to medium sticker shock, but be very aware that especially in this case you are getting what you pay for.

    It is the best system available, period !

    Yes we also know about e bikes which sell for less than a regular Dahon Bike, and substantially less than the Bionx Kit alone. Comparing them to a Yugo would be a slap in the face to all Yugos. There is a lot of junk out there. Buyer beware !

    Getting a Bionx fitted right, makes a huge difference in day to day enjoyment for years to come.
