Jupiter Defiant Electric Bike

Just got my bike and can't wait to ride it! It arrived days earlier than promised and was delivered right to my door by Fed Ex. Very, very pleasantly surprised. Bike set up instructions in the box were somewhat lacking but solved that by simply watching the video on U-Tube. Got the smaller Discovery for my girlfriend, so lots of trips to bike-friendly locates are in store. Thanks
