Don't get no respect. Wife doesn't like new conversion.

[harrys]

I converted this ultra step-thru Biria for my wife, figuring she would appreciate the EZ-on/EZ-off . Used a Q128 rear motor. 20A KT controller. LCD3 display. I even adjusted the seat in the horrible position she likes.



The Biria runs its shifter and brake cable thru the frame, so I ran the 4n1KT harness thru too. The controller box was too awkward to fit between downtube and fender. I put it on the luggage rack. If I find something a little thinner, maybe I'll move it, It will show less cabling behind the seat tube then.

While the bike can pull 1000 watts briefly.I thought the alloy frame dropouts were strong enough to not need torque arms. Throttles are legal here, so it got one.



I kept the original brake levers, which were better than your typical Wuxing brake levers with switches. Fitted magnets and switches to the original levers.

Decided not to use a downtube battery .Main reason is the battery cables would be exposed and run several feet to the controller. I am loath to drill any access holes in alloy frames. So it will be a battery bag on the rear rack. I'll run a 48V 26 cell 21700 pack in there. Should be good for 40 miles easily,

Bike is smooth. Runs nice. PAS 1 is 130 watts and allows easy pedalling at 12-14 mph. PAS 2 is about 220 watts. Haven't run it any higher. Have installed a better mirror and a handlebar bag, not shown,

WHat's the trouble. Easy pedalling isn't good enough. She is used to the "effortless pedalling" from her mid drive TSDZ2B on this beater Giant frame. The TSDZ2B has OSF firmware set in cadence mode. I rode it yesterday and I have to agree that it's much easier to pedal the Giant. It's also shorter and handles quicker.

We'll see what happens. I don't mind riding it.

Maybe it's the wrong colour, or it's just plain ugly. After nearly fifty years I've come to realise that the more I second guess how to please my beloved, the less successful l am. Females just think differently and expect us mere males to know. There should be a health warning about it on marriage certificates!
If it helps at all (probably not), I picked up this hardly used bike and converted it for my wife as a surprise-



Her reaction? "Oh, I don't like that colour"!
In some respects it's the nicest bike in the household, but she's only ridden it once. I've even suggested getting it resprayed (spare no expense) but the reaction is luke warm - her mind is made up and there is obviously some other unspoken reason why.
I've raised the saddle and fitted a longer stem so I can use it on those days when I don't feel like getting a leg over - and that's another contentious subject.
Having said all that, the Giant is a much nicer looking bike than that Biria!

I think I can see your wife point of view. 220W may not enough at times and may be too much at other times.
I think the motor rpm is important. If its too high, then you will get just 220w the whole way across your normal speed range with no tapering off as the speed increases. In my own case, for example, I have a mxus xf15 at 36v/22A with a rpm of 288 (8 rev per volt). I have it usually set at PAS 4 but I often leave it at PAS 5 (750W). The bike at PAS 4 will deliver 450W up to about 28 Km/hr but starts to taper down naturally (back EMF) so that the bike is averaging about 250W consumption although the bike is set at PAS 4 or even 5.
So what I like is the PAS set high but a sort of power curve that starts high (for assistance on hill/wind etc) but tapers down nicely as my speed increases. This gives a very natural feel and gives a feeling of some reward for pedaling. With this set up, I rarely have to adjust the PAS levels and only occasionally use the throttle.

Well Lads i would be pleased as punch if anyone were to give me a new bike and all the above look smashing to me
