Anyone build up a Jekyll 3?

Post by Jay-Fayzed » Sep 06 2013 12:45pm

Hello, first post here. Just wondering what you guys thoughts are on a mid drive, or rear hub on a cannondale Jekyll 3 ? I'm aware of pros and cons for both, but more wondering if I should just build on a different frame. I'm not trying to re invent the wheel and rather follow a proven frame, motor, battery combo. This would be my first build. And obviously I like the jack of all trades kind of bike. I have to commute a lot on it and hit the trails on the weekend. I'm not afraid of pedaling so I don't need something that I can't pedal at full speeds either. Just wondering if anyone has build on this particular frame.
Thanks

What size/ year is it. I built up a older jekyll bad boy ultra and think it was a very good bike to use as a platform. Great commuter. I would love a newer mtn version to build a light weight general purpose mid drive with. Unless your going down hill racing it should work great.

I have a medium 2010 Jekyll , the one with the fox dyad rt2 rear shock and the talas fronts ( 32 I believe ) I live in Colorado Springs which is somewhat bike friendly, but I am going to build a battery pack into a back pack( keep the bike a little more stealth looking )

That is a very nice light well balanced bike for this. My size. :mrgreen: Would love to have one to build up now with a big block modified gng setup. Got hold of a older Giant that I am going through now that is heavy in comparison and does not have as nice of a battery box potential. I would certainly keep the wheels as is, they are much too nice a setup to put a big hub into IMO. I would look at the new 750 watt bafang mid drive if simplicity is top priority. Looking to try one of these myself. http://endless-sphere.com/forums/viewto ... 28&t=50104

GNG works well but required a bunch of work and is much more exposed/ complex. My first build http://endless-sphere.com/forums/viewto ... =6&t=51830

Good luck with the build.

cheers

Thanks for your input. Yeah I thought I liked the wheels too much to throw in a large hub, maybe a small 250-400w but I really love the way it handles and don't want to throw too much weight in the rear. The larger GNG looks promising right now but would need some re engineering to gain my approval in the safety/ reliability sectors. And this would be my first build. I have lots of background in automotive mechanics, and modding the crap out of my kids power wheels and scooters. But I won't touch my baby unless I know it will be a very clean build. My other option was to sell my Jekyll and purchase a mid 2000's DH bike and build in that. But again I really like my Jekyll . It's my first REAL bike I've owned and love it. I can't go back to wal mart bikes again :twisted:

I picked up a great DH bike, but thinking I would prefer something more like your jekyll. Not decided I will sell the DH bike just yet, but looking that way at least for a general purpose mostly road / light trail build.

Ok so the predicament I'm in right now is everything I purchase has to go through the bank (wife) first. And she kindly pointed out that a good 48v 12-15ah pack will set me back 600-800 , and the I still need controller and motor which would be another 600-800. Which is the price of a half decent e bike like the volton/ prodeco. Plz dont flame me lol. Anyway I won't throw cheap parts on my c-dale just cause it makes no sense to put sub par parts on a higher end bike. So should I just buy a e bike mentioned above and upgrade/ redesign as things break( hate battery packs above the rear tire) . Or ........save pennies up to do this right? I have about $600 right now I can use with the OK from the bank. And a brief use of bike is, commute daily 10 miles round trip, weekend I hit the trails here in Colorado Springs , and there are moderate hills everywhere here. Let me know what you think.
Thanks

In case your progression at this point is going to a mid drive style vs. wheel driven. You need to reassess your bottom bracket and bottom bike tube geometry. Just glancing at your bottom frame on that C-dale bike you may be forced into modification of the bracket just to make it fit securely. I could be wrong, though. I don't want you to jump off on the wrong side of the pool. Check out LightningRod's website which offer a better & stronger & adaptable mounting bracket for the GNG kits for both 68mm and 73mm bottom brackets.

Nice bike.

One other thing to think of is where you plan to put the batteries. The forward triangle on the bike in the picture (assuming this is the same as yours) is on the small side. You mention not wanting the batteries over the rear wheel, so you might want to look at some layouts and think about where you can put them. Just a thought, having been down this road.

Alright I've been gone for awhile( had to tie up loose ends in Afghanistan ) and in that time I have soften up the wife a bit and back on track to do a nice build. I still like the idea of mid drive, but I do have a rather unique down tube shape where it meets the bb. So I'm not too sure it will be a straight bolt on application. On the triangle size issue it is on the small side. A few questions to those who may know. If I go rear hub is it feasible too keep the 10 cog? I was riding Falcon trail (long steady uphill sections )a few weeks ago an I saw a ebike with rear hub and single speed gears. He powered uphill with some serious ease and had me thinking on whether or not I should care too much about the ten cog.
Also is there any rumors about any Black Friday deals going on for parts for ebikes?
