a. The basics
Understanding the basics to a bicycle frame size will help in determining the correct positions and adjustments for
your body size and comfort. The G Plus Mariner's frame was designed to easily accommodate all riders from 5' 3"
to 6' 3" utilizing the available adjustments. The frame size can be considered anywhere from an 18" to 23" if
comparing to traditional measurements. The most important information to remember when sizing your bicycle is
that you are comfortable riding, especially when pedaling. With throttled electric bicycles some riders may choose
not to pedal and the measurement will be different than for a rider who chooses to pedal and is the same size.
Scooters for instance have a much lower saddle height than bicycles due to scooters not being pedaled. A higher
saddle height is only recommended for riders who pedal allowing them a full extension of their leg per rotation of
the crank.
b. Frame size
The typical measurement number used today in deciding if a frame size is the correct size for a rider is the seat
tube length. This number usually begins around 17" for MTB style bicycles and can go as high as 25" for Road style
bicycles. MTB bicycles will usually be 10% smaller in number size for the same height rider when comparing to
Road sizes. The seat tube length is measured from the centerline of the crank (bottom bracket) to the top of the
seat tube (seat tube clamp). On folding bicycle frames using 20" wheels, this number will be much smaller due to a
manufacturer's desire to produce a compact bicycle when folding. The seat post will tend to be longer on these
frames to offset the difference. There is another measurement sometimes forgotten which is actually more
important, this is the top tube length (seat tube to the steering tube). Most manufacturers will proportionally adjust
the top tube length according to the seat tube length and with stems being available in various lengths, fine tuning
of this measurement is easily accomplished.
Prodeco Technologies G Plus Mariner's frame measurement will differ from traditional bicycle frames due to the
seat tube being longer than a traditional bicycle and the stem being at centerline with the steering tube.
The G Plus battery base required an added mounting area to the seat tube, therefore the better way to measure the
seat tube is from the base of the saddle clamp (seat post must be inserted at the lowest position) to the centerline
of the crank. When measuring this way, the G Plus Mariner would be considered an 18" frame. Even though
considered an 18" frame, the frame is unique in other areas, allowing for all size riders and adjustable to be similar
to a 23" road bike frame.
