Agutta 1st Impressions

Kalkhoff-first Impressions

BORIS(well got to be its name right?) arrived this morning.
Having charged up,fitted pedals,and aligned H bars did a quick around the block.

1) Build quality excellent.
2) Frame size (53CM) perfect for my 6Ft with 31.5" inside leg
3)Riding position, sit up-and -beg ,perfect and very comfortable.
4) Power assistance levels appear to be just right; used low all time, and high on a very steep slope,which made it a breeze.
5) As an old ,unfit biker,who needs help, and likes quality,
this is the machine.

I would like to publicly thank all at 50Cycles, who have been most obliging (and patient) and say that , in my inexpert opinion, they have a total winner.
I look forewards to A 2 B ,and Fleccs reviews in near future.

Boris. Russian eh!

I think mine's more of a Gunter in scale, despite now receiving a low seatpost to make it possible for my 5' 6" to ride it without developing cramp.

Glad you like it Chris, nothing not to like really.

[Chris]

No Flecc-not Russian-surley a gentleman of your tender years remembers Boris Karloff, of the Pinewood horror film era?

 

[flecc]

Of course, a pseudo Russian.

I can't remember his real name though.
.

 

[Chris]

William Henary Pratt-no wonder he changed his name
Chris

 

[flecc]

Ah yes, I remember now. That name just didn't go with the character acted!

I used to see him and the rest of the gang around Hammer Films in Wardour Street, Soho, when I worked around that area years ago.

hi on the handle bar switch the bike seems to have low medium and high power but what is the mode switch controlling if indeed it is a switch

The mode switch sets the amount of power IE LOW MEDIUM OR HIGH.
The other switch is on/off

Wardour St.-did`nt it have a certain reputation?
Chris

 

[flecc]

The whole of Soho did and does Chris, but I was born there and christened there in St Anne's Church, so for me it has entirely different connotations.

[Chris]

Well,I originate from Coulsdon-in the days when it was a proper village-now part of the sprawl!
Chris

 

[jac]

thanks now i understand

Just down the road from me now, but I don't cycle that way with the A22 rat race in the way.

[Cyclezee]

Oh, I must apologise on behalf of my friends, they seem to have got side tracked and lost the plot on this thread
Think the Guru has been at the WD40 again, or should it be WD70

 

[flecc]

Eh? Isn't this the "All our yesterday's" thread?

Or was it the " Who do you think you are?" thread?

[Chris]

Back to tarmac then.
The one aspect of the Karhoff that I would like to see is,"on the bike charging",also the charger is a "lump".Dont feel to strong about this-would have been nice though

Possibly a design problem Chris, nervousness about high currents getting into the rather delicate areas of the Panasonic computing board. Same on the older Lafree/Panasonic system.

mainboard

I suppose the charger is a matter of fashion, the type popular with power tools/hedge cutters and the like now. Too cumbersome to carry though, so I agree that I'd like a more conventional free lead rectangular box.
.

 

[Chris]

Thanks for explination-but-how do Ezee overcome the same worries on their mainboard?
Chris

 

[flecc]

It's just a straightforward controller Chris, tiny by comparison since it has nothing like the computing power of the Panasonic system which is unique in E-bikes. The Panasonic board has much in common with a computer motherboards, including a CPU and EPROM for example, and rather sensitive electrically. The method used for pedal torque sensing uses incredibly small current variations, a million miles away from the crude rotor pickup systems used on hub motor bikes

Only in the power handling area is there much in common.

Understood.
