99cc Predator in a Nirve B-1?

[maurtis]

Thinking about my next build, I am definitely leaning toward a 99cc Predator. Mated with a Qmatic, it seems like it would have the reliability and power that I am looking for in a motorized bicycle...

Since I already have a cantilever framed bike for my HT, I was thinking of going with something a little different for this build. I really liked the Nirve B-1 when looking for bikes for my HT build, and can get them locally.

Anyone with Preddy experience think one would fit on the B-1? The closest bike shop that carries Nirves does not keep them in stock, so I cannot go measure unless I actually buy one.

Remove that metal insert between the top and middle bar and make an in-frame tank, swap out the bars and you should have a pretty nice ride...

You might not have to do all that work... I know that the Predator 99cc fits inside a Schwinn straight-bar frame without modification, as long as it sits low. Having said that you'll need a wide crank set to clear the motor if you plan on pedaling still. I haven't seen a B1 in person either so I can't give you an honest judgement. My guess is... it isn't as small as a Workman frame, but just as much if not slightly less of a belly as the Schwinn's.

Its been awhile but I did build a B1 once (2-stroke). In fact i sold it to nice young lady who use's it to get to class at the University of Arizona.

She comes by once in awhile just to chat or for me to do a little work on the bike. Next time she comes I will do some measuring for you if I remember to do so.

Thanks Dave! Your thread was one of the ones I was eyeballing when contemplating using a B-1 for my HT build.

My main concern would be the Preddy being a little too tall to fit under the middle/lower flat bar.

Using a picture from your thread, it gives a good example of how an HT fits. From that, I might be able to compare the height difference between a Preddy and and HT. Looks like there was about 2" of free space above the HT?

I am thinking I might have to tilt the Preddy a little...

Thanks for the reminder about the wide crank, I definitely plan on keeping the pedals to pretend it is still partially pedal powered. And it is always good to have a backup, just in case...
