"The Stealth Bomber is definitely among the highest quality, fastest ebikes offered as a turn key ready to ride machine. The Stealth Bomber is fast, agile, quiet, long range, and cool looking. What’s not to like?"
"This bike has 2 major drawbacks. One is the $12,000 price. Second is the weight. 116lbs (63kg) is considered super heavy even by electric bicycle standards, and a lot of that weight is in the unsprung back wheel."
Their promotional video is extremely entertaining.
