The G Plus Mariner's crank is forward of the seat tube and the G Plus Mariner also has a higher than normal seat
tube angle. A crank being mounted in front of the seat tube produces a sit up riding position and allows for the seat
tube distance to steering tube to be enhanced while maintaining a compact folded dimension. With the higher angle
seat tube, as a tall rider raises their saddle to accommodate their longer legs, the saddle will pull back offering a
longer distance to the steering tube. For fine detailed adjusting, the narrow seat post saddle clamp allows the
saddle to be moved back or forward an additional 7.5mm each way.
c. Recommended sizing
In today's bicycle industry, the top tube length is actually more important than the seat tube length. With seat posts
now available over 300mm, the seat tube length is no longer the most important number. The distance of the
bottom bracket to the road can also mislead the seat tube length. The top tube length is traditionally the distance
from the center of the seat tube to the center of the steering tube. For purposes of sizing the G Plus Mariner, we will
name the distance of the center of the saddle to the center of the handlebar the steering length (similar to the top
tube length).
You can adjust the steering length of your G Plus Mariner by establishing the saddle position and handlebar height.
The saddle position can be adjusted for height and distance from the steering tube via the quick release clamp and
the saddle clamp. Keep in mind by increasing the height of the saddle; this will also increase the steering length
due to the angle of the seat tube. Below is a chart recommending the adjustment of the saddle height and steering
length for your size if you will choose to also pedal your G Plus Mariner. This chart is only a recommendation and
you should choose the most comfortable position for your style of riding and size. In many cases, persons of the
same height will have shorter or longer legs and also shorter or longer upper torsos. Please also keep in mind
when sizing, the G Plus Mariner has a suspension seat post and this will alter the saddle height dimension based
upon the rider's weight.

(a) The steering length recommendation is the distance from the center of the saddle to the center of the handlebar
(b) The saddle height recommendation is the distance from the top of the saddle to the pavement
If you choose to use your bicycle as a scooter style vehicle only, you should establish saddle height at a lower
position to reduce the center of gravity. Saddle height can be reduced to 1 inch under your inseam. Your inseam is
the measurement of the inside of your leg. The steering length recommendation would not change and the
measurement in the above chart remains.
d. Control position adjustments
The G Plus Mariner includes a twist and go variable throttle with an LED battery indicator on the right side of the
handlebar and a thumb sliding lever bell on the left side of the handlebar. The throttle can be adjusted on the
handlebar to rotate further up or down (you will need to use the 3mm hex key included with your G Plus multi-piece
tool kit). The brake lever assembly and throttle mount together and at a certain point of rotation, one will not rotate
further without the other requiring to be rotated. If the factory settings on the throttle are uncomfortable for you or
