Choice of bike frame - dilemma solved

Post by Tiberius » Apr 21 2008 10:27am

Hi All,

I have been thinking for a while about what type of bike to electrify. You may have seen some postings to this effect. Toshi was considering converting a road racer, but I think he has changed his mind. The argument was that on one hand a road racer is the best for weight, aero drag, etc, but on the other hand most people here recommend a full suspension MTB.

Anyway, there was a simple answer in the end. This is as much an experiment as an intent to hit the spot first go; I may well end up doing another. I already have one ebike, eZee Torq, so the solution was obvious: If it is research, then at this stage choose the option that is most different from what I have already. So I got this off ebay:

Image

The rear wheel is 26" with a 6 speed freewheel and 140 mm spacing. Looks like ideal for a Crystalyte. So compared to the Torq it will be
Rear motor instead of front,
Folder instead of fixed
Front 3 speed deraillieur instead of 1 speed
Full suspension instead of none
Able to climb steep hills

Someone else appears to have come to the same conclusion.
Looks very similar to this turnkey model.
But you'll definitely have a lot higher performance.

Definitely some similarities there.
Do you have any more information on that red one? Oh, and where are the batteries?

OK, found it, thanks.
Love this bit from the website:

Pedaling also helps charge the battery, this provides you the freedom to ride to and from almost any destination.

Just like a non-electric bike?

I can do the magic eye thing, and I STILL don't see me. The wheels look pretty funky when you try, though.

That's because they are both electric.
Its an interesting concept, sucking energy out of the rear wheel and giving it to the front one.

:lol:
what boat?
I only see link.

Tidalforce is the reverse.
Battery in front, motor in the back.
Most don't like a hub bat cuz of the myth (don't know what else to call it) of unsprung weight, but strangely don't have the same reservation when it's a motor.
It's not that big a deal since the rider is the largest concentration of mass.
I'm partial to a hub battery as there's not a lot of payload space available on a bike I'm not willing to turn my back on a half kWh of free space.
I need my rack to be free to haul stuf, otherwise an ebike would be of limited use to me.
The thing I'd like to see on bikes with a large beam like this one is to expand that top tube even a little more to serve as tub for in-frame battery storage like the Optibike giving you complete stealth.

Myth? Geh? I've noticed a significant difference is how hard bumps push back against my hands after I installed the BD36 hub. Has a lot more kick than it did before. I couldn't even imagine putting something super heavy like a Golden Motor or an X5 on the front.
