Just under 4 years ago Specialized had an " Open House " event, In Morgan Hill, where you could tour their wind tunnel, view the new models of that year talk to people in the business and ...
Test Ride their Turbo hub motor electric bike.
( I am not in the Bike Business so that event was much appreciated by me, I wish they would do it again )
In the previously two years before that I test road every electric bike from sellers/bike shops that was being sold from San Jose up to Redwood City.
All those commercial e-bikes were expensive and had pathetic performance, or should I say, No performance .
So now to the Test Ride on the Hub motor Turbo just under 4 years ago.
Having hills around the Specialized HQ I decided to put the , what is now the older version Turbo , to a real test, I road up some local hills .
It was the Best Commercial E-Bike I had ridden , it performed better and went faster than all the others. ( It did have the electronics tweaked to bypass the low power European Rules and was now within the American 750 watt and faster speed allowed.
However then and now as well , they are way over my budget.
And there were no used ones available at that time that were under $ 2,400 Used,
So
I did my own conversion .
At that time there were allot of problems with the BBS01 and BBSO2,
So
I went with the Mac hub motor, and am quite happy with it.
I must say though that the Specialized Turbo that had the electronics adjusted to better performance spec's is every bit as good a bike as my Mac Build. and Cleaner Looking as well
My Mac would probably make it up your friends hill, it is the 6T version, and the 12T version of the Mac rear hub motor would work for sure.
Now in regards to that bike shop, and a 3,500 Specialized E-Bike.
The Turbo Vado 2,0 is $ 2, 700 and the Turbo Vado 3.0 is $ 3, 200 so that must be the one ? as well as living in a high tax state.
It is the fault of the bike shop to not sell her the newer , Mid-Drive , Version of the Turbo, I think it is called a Turbo Levo .
There is a Video Review of the Newer , Mid-Drive Turbo Levo that is done by the young guy that does most all the bike reviews , ( electricbikereview.com)
In that video you can clearly see that the newer Mid-Drive Turbo Levo will make it up any hill.
I know the area where that test video was done and those are very steep hills.
So really the Fault is mostly likely with the Bike Shop that sold her the wrong bike in the first place .
I get to see Specialized bikes every day I am out on the Road riding my bike, and what I see is some of the best bikes around, their Performance Road Bikes are just incredible even at the $ 2k $ 2.5k price range .
it does however cost money for R & D , testing , etc,
then factor in the fact that all the Specialized ... E-Bikes are designed in Switzerland, that is one of the most expensive Counties in the World so that adds allot of cost to one of their E-Bikes.
And when you want a Swiss Watch or something else from Switzerland, you are going to have to pay a premium for it.
The Fit and Finish of Their E-Bikes are far better that what you or I can do with our DIY Conversions.
Had your friend gotten the right bike in the first place ( The Mid-Drive Turbo Levo which is $ 4,500 at my local bike shop ) your friend would have been quite happy, and would have been happier in the long run than your BBSHD, as it is cleaner looking, will go over taller logs and rocks, and the Turbo Levo will have a much better resale value as well. ( A much better / higher Resale Value than a DIY conversion )
So in the Long Run the Turbo Levo FSR Fattie 6 / 29 ( it is really a + bike 2.8 inch tires, not really a fat bike ) It Would/Will be a better bike.
