First (eBay) Build from the Ground Up
I am from Bermuda, but currently live in Croatia, and I am not used to being shut in all winter and I needed something to keep my hands busy.
One day I saw an old Mobylette AV88 frame for sale on eBay Germany and I bought it. (no forks, swingarm, shocks or fenders) Then I needed an engine to suit, which I also saw on eBay.de that had a 70cc kit with a race clutch & pipe, so I bought it.
Motobecane “Mobylettes“ are French mopeds, they were very popular in Bermuda for renting to Tourists in the 60’s & 70’s. I used to have a Mobylette when I was a teenager and scrambled it around the yard.
I had seen a few pictures on the internet of custom mopeds that looked like mini Cafe Racers and knew I wanted to try to build mine in that style. So, I began collecting parts from all over the Internet. I only had a bag of tools and no workshop, so I emptied the small Garden Shed of everything I could and moved in a workbench. I had never build a bike from the ground-up before, but that didn’t phase me as I grew up around Mopeds, so I just went at it and what I didn’t know I looked up on the Internet. I bought a drill & a vice about half way through the build and I now own a disc grinder.
As Croatia is now part of the EU it is relatively simple to order parts. I sourced after market Race Forks, Lower Shocks, Magnesium sealed bearing wheels (so had to get high speed tires), Front Disc Brake assembly, Front fairing and a Cafe Seat. The racing square swingarm is from a later MBK 51 model, but fit perfectly, and has a side stand. I went to a 12v CDI system and bought a new Doppler ER2 Clutch Pulley, which lets the engine variator & belt spin in place, so no pedals required. I had also never wired a bike before, so this was a first.
I did get some outside help; I sent the frame, swingarm and a few bits to a professional for final paint and a mechanic friend got the wheel and disc spacers made, to my measurements, and had an aluminium manifold extension made so the carb didn’t hit the frame when it variated. I did test everything out before paint, at a local track parking-lot with a different pipe, and got it up to 80km/hr before I ran out of space.
This was about an 18 month build and it eventually evolved into what you see today.
I like that I am a BERMUDIAN that built a FRENCH bike in CROATIA all from the Internet!
I named it “Kaffe 88“ as a nod to its German (eBay) origin.
