We're exploring whether the Clem L would allow the mounting of a EM3ev 36V (10S5P) Super Shark Ebike battery on the "top tube". If so, we'd link it to a geared front-hub motor. Has anyone tried to mount such a battery to the Clem L?

I haven't but you should be able to measure and guess. I looked that battery up and the length is 368mm or a about 14.5 inches. Now the problem you're going to have is determining how that battery will fit between the headtube and where the curve kicks up on the toptube. If you have 17 inches to work with I think you're good. Less than that is pushing your luck without actually having the battery there to try, in my opinion.

Also check the unit's cable lengths, that they will reach around.

Yes, and  what worries me is the "sliding distance" required before secure attachment of that battery. Btw, I'm very attracted to the Riv GBW. Talk about placing the body inside the cockpit instead of perched upon it!

Dave, who has a MIT Sam Hillborne similarly equipped right now (and with 40mm Soma Shikoru tires), but who is wishing for 2" cushy tires to more safely navigate rough urban streets.

Yeah, you'd have better luck with that battery Luna sells that mounts to magnets..you can slide the battery up and back more to get it to fit. But bollocks on that, a GBW would be a great eRiv!

Which size Clem L?  I had measured mine for a Bionx kit and it looks doable by adding one braze-on south of where they placed the original water bottle braze ons...

Mind you this is an OG size large Clementine...so could be different than the current offerings.

I was going to use a brass rivnut for simplicity.

Ours is a 52cm Clem L. Would you supply me with a photo of your installed brass rivnut?

Never ended up using that system... opted for a Copenhagen wheel instead.

Get a rear rack and mount the battery there. I have a large downtube battery mounted on a Riv similarly and it works great. I have ridden bikes with downrube batteries mounted to the frame and the weight distribution when mounted to a rear rack isn't very different, especially on my Atlantis.

Chris, did you strap your downtube battery to your rear rack using its downtube radle to secure it? Any special technique?
