Just watched it on the tube last night..

Now that was one radically sweet looking machine!!!

They didn't have much on performance information or the programming of the controller like I was hoping.

Was said to have a 60 mile range (if I recall correctly) - as well as more than 100 MPH top end (a lot faster than I would have thought given the apparent gearing)..

My eNinja project may have to wait now!!!

That looks amazing, surely it must be running a high voltage if they are quoting 100mph, and for a 60 mile range wouldnt they be needing a fair few battery packs wired up to achieve such performance? If so they have either been very well hidden, are extremely small, or the bike doesnt achieve that sort of range and speeds.

Aloha, they exaggerated, Under the hood it is very low-tech.
but looks good.

I believed that they did do some exaggeration.

It may well do 100 MPH, but it won't do 100 MPH and have a 60 mile range.

Low tech? I don't think so. Just because it uses an integrated controller module and Charging system - I would not call it low tech. On the contrary. When considering the very basic ICE world of Choppers, this is a very hi-tech piece of work.

LOOOL...physicaly it is NOT possible to go 100mph with only 27HP...

LeadAcid-batteries....====>>> LowTech...

60miles range with leadacid...LOOOL

everything, what OCC is doing in LowTech...

I take exception to that "First custom electric chopper" statement; and I know mine wasn't the first either.

And by what do you base this opinion?

LeadAcid-batteries....====>>> LowTech...

AGM is a long step up from simple wet system Lead-Acid. Certainly not to the degree of lion though..

60miles range with leadacid...LOOOL

Many EVs will go a very long ways on level ground and reasonable speeds and temperatures. This is probably a stretch of the truth for real world - but for perfect conditions, it's achievable.

Show us your HIGH-Tech so we have a point of reference please.

[RoughRider]

there are some basic equations to calculate the power that you need, to drive a defined speed...you can get this equations from every good physic-book...

i am not saying, that i have high-tech in my garage...

BUT..this OCC-thing is far away from high-tech

[etischer]

Siemens was an OEM for AC motors and inverters for companies like VW and Ford. I think the technology in this DC bike is pathetic and so 1980s. I love how they mention that a Siemens company made the LEDs on the bike, why didn't Siemens provide an AC servo motor and controls?

Maybe the Osram LED company can hire someone to build a fancy flash light using incandcent bulbs and AA batteries made by one of their parent companies.

It is a TV show. Entertainment
