I think takin jus' the back off the Glendale, leaving some of the seatpost tube as flanges to weld would be less sketchy than tryin' to weld in a different Dtube just so the motor would fit... much depends on the quality of the hardtail bike and the skill of the welder ofc.
I suspect that the uneasiness people have regarding aluminum bikes may stem from bikes that had a poor design... perhaps an inappropriate one - like takin' a lightweight street race bike and "abusing" it by riding down stairs or w/e. My Schwinn started life as a mountain bike - after over 4000 miles of motorized use it's not showing any signs of fatigue.
I think that like with any bike yer plannin' on motorizing - a bit of an examination, lookin' at welds and thinkin' bout it's design is all that's needed *shrug*
Well said. You're right, it would seem the design is as important as the material and the weld quality.
