Motobecane “Moby” is a cornerstone of 1970’s mopeds
- millions have been sold worldwide since they debuted in 1949.
(Today Yamaha owns Motobecane and the 50V is still manufactured
for sale in France.).
is a real pleasure to ride these mopeds; they are quiet, smooth
and, (variator equipped), have the best all around performance of
any moped I have ridden. The variator is a pulley controlled by
flyweights allowing the belt to ride up or down the inside face
thus changing the gear ratio. (The entire engine pivots to take
up slack in the belt.) Braking is excellent and overall the moped
feels very solid and comfortable. They also have a easily acessible
tool box and well equipped tool kit.
By the late 70’s the list of options available from Motobecane
dealers was very impressive, this bike sports many of them including
the leg shields, special handle bars, long seat, fold-out chrome
baskets and rear-view mirror. Motobecane USA also offered nice vinyl
saddle bags, a handlebar extension rear view mirror and windshield
among other options.
down side to Moby’s is they are French - simply miserable
to work on and repair with the engineering being over-complicated
and counter-intuitive. Many jobs require special tools/know how
(manuals are a must have) and parts are getting very hard to find
here in the USA. The specially designed drive belt must be replaced
with an original Hutcheson belt (available only in France as far
as I can tell) or the bike will not perform correctly - a run of
the mill Gates belt will reduce your top speed by 4-6mph. Another
downside is the fuel economy; horrendous at only 50-75 MPG.
