Brompton Electric Clone

Just saw it online , a Brompton Electric Clone. I believe it is made in China factories. The wholesale price( battery excluded) is 500 USD. Wanna hear some opinions from you guys.

Since they so faithfully copied the Brompton, I would assume it's in the luggage bag which is not shown.

Well the bike does not seem to have a carrier block. But there are some cables inside the frame: https://ibb.co/fRMchG
Would possibly be a tiny battery if this would be it.

What kind of crankset/botton-bracket is this?

So is there any way to buy this thing, or are we just going to debate battery location for 6 months?

James Starley invented the tangential spoke pattern in the 1870s. As they discovered on the old penny-farthings it is much stronger than radial spoking when transmitting torque. Small diameter rims and large diameter hubs are progressively more problematic to build into wheels as spoking pattern approaches tangential. Solving this problem by going to a radial spoking pattern for a front hub motor - as I see done on a great many small wheel ebikes - is probably not a great idea. The better manufacturers do one-cross in this application.

Good point. Those are badly built.

500 dlr sounds like another bike, albeit more but bigger and supposingly built with titanium tubes

The Brompton Electric front wheel appears to be radial spoked...

Not exactly. They've used an interesting, unique 'splayed, paired' 28-spoke pattern on the Brompton. Durable & robust? I dunno, but clearly some thought went into it.
