Certainly looks like it would fit within the frame if the water bottle cage was moved.
Easy to mount a WB device behind the seat I would think. One other thing, get some paint
or vinyl graphics on that motor!
Got a pl250 in on Friday. Mounted the bat lower outside water bottle mount. Fits good although I had to make some small plastic pucks to set the at holder off the frame a bit as the mout is more ment for narrower frame tubes.
system seems to work great. Wish they had a mount for the display that would be better suited to my bent MTB bars. Dispay sits on a tilt rather then pointing directly at me..
Used the water bottle screws to hold the mount on. And added some velcro straps to give it some extra support (seeing the battery is roughly 6x heavier then a full water bottle which is what those screws are probably designed to hold)
Best part i suppose about mount it there is the CG of the bike is kept very low..
Also the 9spd freewheel with the 11 tooth small seems to work well also *found it on ebay* So that is good news to. Although the big sprocket is several teeth bigger then the big one oon my casset. So it does not like running on that sprocket in combo with my large front (not that you should be selecting that combo anyway).. and becides with the electric assist you would not be in that gear for long anyway.
Now to figure if the battery will last long enough to get me to and back from work (with my peddle help of couse)
Here are a couple shots of the bike with the system installed..
If anyone can suggest a better 9spd freewheel then the one I got (with a 11t small) I'd like to know a supplier I could order it from. The quality of the one I got from ebay isn't exactly what I had hoped. Considering the price and such it is fine but I'd love to know if shamano actualy makes one or some other brand.
Gearing up for my first ride home from work tonight. So will report on how it worked will come.
Well still have some kinks to work out and have to get used to where this will increase my average the most. But on my first ride home I increased my averate by .4 mph over my fastest "peddeling" average.
Although I had a note in my log on that particular day I had a serious tail wind. Typically I average around 14.55 so actually this improved my speed by 2.15mph
My average today was 16.7 although my light timinig was all screwed up vs the way I've sorted them out when on peddle only speeds. So my actual average when I was moving was probably faster then that.
My average time over 12 trips is 51.5 min. Today I did it in 44min again I was waiting at more lights then normal..
I'd sware I was working harder this ride then on regular peddle power over all.. So in that respect I'm a little confused. Perhaps it was the fact that I was pushing it pretty hard to do as fast as I could and it was 88 degrees out.
I think overall I'm going to want to get a PL500 so the assist continues past 20mph rather then leaving me peddling like mad to maintain 19-20 once it helps me get there and drops me off
One thing is for sure. You don't have to worry about gear selection quite as much when starting from a dead stop. And you can jump out infront of cars a LOT faster then they are expecting (acceleration help)..
Is it cool? I'd have to say yes. Just not sure how cool. If I can be assured a 45min commute no matter how tired I really might be, I think this will be a winner. Although I wanted to get it closer to 40 or 35min..
this PL 250 might find it's way onto my son's bike.
Second trip into work I did a bit better. Getting used to the unit a bit more.
Battery charge indicator is at 4 blips remaining. and clocked 24.8 miles on this charge. So might be on the way to the 40 mile range (or over shoot it a bit) if it continues to track battery state of charge in a linear way.
Assist level has been full on all the time (although the real time assist graph only has 0-3 lines on most of the time so really does not look like i'm "using" the battery that much.
In anycase I'll charge the bike while it's here at work in anycase
averaged 17.9 mph on this trip. (so that is an improvement
Lights timed much better.
Less wind over all (morning)
41:45 travel time (getting pretty close to an even 40min.
