• Altering the Top Speed is possible. This will be a long and technical answer. The ecoLove is supplied with a 9 or 10 tooth chain sprocket and a 22 tooth freewheel. We consider this set up ideal for general city driving and minor hill climbing. Upon request, we can also supply a 11 or 12 tooth sprocket in place of the standard sprocket. With a larger sprocket, the top speed will be increased to about, and acceleration will be reduced and some hill climbing ability will be lost. Range will also suffer if you maintain high speeds without pedaling (See explanation below). Although we consider the factory set ups to be ideal for the design, it is possible to change the drive ratio, and thus alter top speed and acceleration characteristics. Before attempting this, there are several aspects which should be considered. The factory set up provides both, some hill climbing abilities and a top speed of about 18 kmph. The drive system has an overall speed reduction ratio of about 12.5 The motor
