To examine the effect of nucleosomes on in vitro transcription, purified chicken erythrocyte core histones and plasmid DNA bearing the Xenopus 5S RNA gene were assembled into nucleosomes and used as templates for transcription in a Xenopus oocyte nuclear extract.
(it could squeeze 100kms out of a liter of fuel) Soon Ducati started bulding a frame to the engine and thus the first official Ducati motorcycle was born. It was a 60cc bike with a top speed of 40 mph and was officially named 50M. The year 1952 marked a cornerstone in Ducati history.

It is easy to make a homemade bike that goes over 45 km/h while still in the 500 watt power limit. The range depends almost entirely on the size of the battery pack. Most commercial bikes skimp out in this regard and (advertized claims aside) can only go 20 to 30 km under typical use. A high capacity pack will store over 500 watt-hours and gets closer to 40-50 km.
