As much as I like a torque assist Pedelec for mtb and how it works and keeps the weight balance centralized and low for off road use I far prefer a hub motor for my road bikes. Primarily because with the higher cadence associated with road riding, and yes I ride lot's of gravé, the Pedelec system doesn't feel natural to me at those rpm's and so I use a front hub motor with no PAS which leaves the drive train up to me as to how I want it to feel.
I do think that the current crop of eRoad bikes is not headed in the right direction based on my personal 5k of riding time on my bikes. I have the bikes set up with at throttle, gasp, that makes the motor my b**ch. Through my display/controller I can set it to cruise control mode so that I can adjust it to the amount of power I want based on my cadence, range goals and terrain and not have to constantly fiddle with it. The system I use has the ability to set the watt limits to 250/500/750/1000 also and truth be told I mostly ride in the 500w mode. A bit more sluggish off the line than the higher watt settings but once you get up to speed I am generally using half that or a bit more. I can climb steep roads at a reasonable pace @ 350w and use my input and gearing that allows for a sort of symbiotic relationship between me and the motor and never feel like the motor is overriding or underperforming.
This is all in the interest of range and the display I use gives me actual information on the amount of watts I am using at any given time and also the ah's used which let's me know based on my experience with the system just how far I can go and how fast I can go to get there. Calculates my wh/mi on the fly also which is like mpg for a car and helpful for range calcs on the fly.
As fast as the e system thing is developing I also am able to adapt my bikes to emerging technology as it occurs rather than having to buy a whole new bike. I am not all that concerned about internal batteries and "stealth" look because I came out of the eBike closet quite awhile ago. I am after the performance I want and not having to spend a bunch of money on basically. Both the bikes pictured below came in at under $2500.
And another bonus is that putting together these bikes I have learned how e systems actually work and can do the maintenance on them myself.
