I been reading posts on here and am convinced this is the best place on the net to get help with my first ebike upgrade by far.
My main goal is to do 10km commute round trips, with about 8 stops at lights, and I want to do the least amount of pedalling needed (this is my vision currently at least).
I hate stopping at traffic lights and having to pedal hard to get going again and it really takes it out of me often to the point where once I get to my destination I can't enjoy my self etc as I am too hot and tired. So ebike is the answer!
I think I would be quite happy with 30km/h speed but am willing to accept 25km/h for exchange for more take off from traffic lights torque. Anything above that would just be a nice plus I think.
I want to electric my Giant Farrago 2009 M sized Hybrid bike and I am having trouble with which type of motor technology I should use.
Here are the specs to for my bike.http://www2.giant-bicycles.com/en-au/bi ... tions_id=4http://www.cbdcycles.com.au/bikedetails.php?id=44
Originally I was thinking of going front geared/direct fork hub, but I found my bike completely fails the magnet steel fork strength test, the forks are pretty chunky aluminium though.
The forks are SR Suntour NEX 4610 V2, seems to get a lot of hits on google.
Then I thought mid-drive Cyclone or GNG electric kit, so i get more torque, this kit looks like a pretty good deal.http://www.gngebike.com/450wbrushless.htm
Then I read mid-drive kits are noisey, and also a bigger job to install, while I plan to only ride on the road so noise can only matter so much I do like the idea the of being discreet, but any positive feedback on going down mid-drive route would easily help make it the choice of path.
I am now really am thinking geared or direct drive rear hub motor, because it will be safer with my aluminium frame and because after changing my rear tube it went flat again after one ride so I am think it's a sign that I should go with a rear setup.
My rear tyre has got a few small holes where I think it's been allowing flats so I think I could kill two birds with one stone and get a tyre+tube rear motor hub kit.
Have been thinking of going geared hub but they seem to cost a fair bit more and not many sellers about locally there is one seller on AU eBay but his listing has currently gone.
So I am thinking it might just be more worth while to get a cheaper direct drive of larger watts to make up for the lost torque of a geared hub. I do plan to give my self a leg push to start rolling and a crank when I start at lights, this should be enough for a direct drive hub?
One of my most important questions is since I have 9 sprockets/gears? on my current rear wheel, does it matter if I buy a hub motor kit with less sprockets? (check my skydrive url pics below)
I noticed most rear hub motors have 6 and some offer 7 if requested.
And what about the fact I have 3 sprockets on my crank?
Also does it matter if I get a rear hub with a disc break and not use it, I was thinking I could take it to a bike shop and get the rest installed for a working hydraulic breaks later.
I saw on this web site the seller really goes on about the importance of "C" Rating of the battery.http://www.edealsbargains.com.au/page2.php
Does this really matter for Hub motor kits or is it important for really hardcore builds? Or is it more important for mid-drives?
I noticed that most of the batteries other people sell are just 2-3 C so I figured it can't be that important, or can a lower C rating performance loss be moderated by buying a higher voltage kit? I don't plan to do any over-locking of my kit I will instead just buy a more powerful kit if needed. Also I am not worried about local wattage/power laws.
Here are pictures of my bike with a ruler, while some pics the ruler doesn't look like it is in line with the fork etc it should be.https://skydrive.live.com/redir?resid=B ...
