60 lbs is not terrible for an e-bike. The extra pounds don't matter so much with electric assist.

Also, the wider tires don't add resistance.

I like the 70s style (and the copper finish on the edition limited of two bikes .... wonder what that cost?) but this thing is overpriced for the level of tech. If these guys put as much effort into e-bikes as they do hyping stuff on YouTube they might make a nice bike one day. As it stands this is simply overpriced. The narrator thinks he can just call it the "best electric bike" when it's obvious that he knows F-All about the technology. There are much better e-bikes for the money in this niche (within a niche) category alone.

Their 2018 Super 73 is $3200 vs $2750 for the Luna Super Banana

• 1000 watt vs. 3000 watt
• 48V 15.4 Ah (740 watt hours) vs. 72v 11.5 ah (830 watt hours)
• 25-27 mph vs. 40 mph

... for $2,300 the Luna Banana BBSHD has similar specs (more likely to be street legal) and still smokes the Super 73 in performance.

Or get the donor bike for $1,150 and add an electric kit for a few hundred more. (which is exactly what Lithium Cycles did!)

Those figures are wildly inaccurate and only apply to grain fed beef (which I do not recommend)
