Hybrid with torque sensor under £1500 or convert existing bike?

Interesting so it doesn't feel the same as a direct drive torque sensor? Would that be the same for the other rear hub motors with torque sensors?

I’ve never ridden a bike with a direct drive motor, if that's what you meant (usually the motors the size of a dinner plate that go over 30mph ridden by deliveroo riders). The smaller, legal hub motors tend to be geared i.e. have internal gears to maximise torque at the lower speeds.
I've also not ridden any hub motor ebike with a torque sensor, only mid drive bikes.

My Orbea Gain just has a cadence sensor on the cassette, but still manages to deliver a very natural feeling ride. The issue I had with the controller on the Woosh kit is summed up on this post I posted on another thread.

However, Woosh bikes do sell torque sensor based kits as well which would meet most of your criteria, although the weight is quite high, 3.3kg for the XF08 rear hub motor, 2.8 for the XF07 front hub motor, plus your battery of course.

Yes it is the torque sensor kits from Whoosh I'm interested in though also good to hear the Orbea has a cadence sensor that can feel natural.

The direct drive DIY motors with torque sensor I am looking at can all be had in some kind of UK legal form I think?, they are ​

TSDZ2B - which seems to be an older well established motor that has had issues with heat and needs fiddling with the software to sort but is then quite reliable and pretty cheap. Apparently there is a larger newer TSDZ8 which handles heat better but has only just come out so reliability is unknown​

CYC Photon - which looks great and is smaller in size but is £1000 plus battery

ToSeven DM02/01 - very new but looks promising, the smaller DM02 is nearer the size of the Photon but much cheaper, can be had for about £300 although there are no UK suppliers yet so that would be sent from China and may well have customs duty on top and obviously no local support if things go wrong. It looks like the latest firmware has got that motor working very well though and is tempting although a bit of a risk

As you can see I've gone down a bit of a DIY rabbit hole, the allure of buying a kit is that my dad could still use his Whyte bike which he loves, and it can be moved from bike to bike and bits replaced if necessary - worry that many of these factory built are trickier to fix when out of warranty. Am happy to be wrong about that - in which case the Carrera and the Fiido are the 2 most appealing.
(Apologies for the weird formatting and bold bits, not sure what's happened there)

There is also the cheaper TSDZ2B torque sensor motor although it seems to be less reliable and a lot more fiddling than the Photon - is that fair/true?

My wife's bike has a TSDZ2 motor kit fitted several years ago. It has been reliable, quiet and just the ticket to get her into regular summer riding.

Did you have to play around with the firmware to reduce heat issues or has it been ok as is? Would only be after a boost to normal peddling, not expecting it to speed my dad up hills off road or anything too exciting

A bit late in posting this but:

Now at age of 82- here's just a little input.
I believe from reading the above I sense you are in danger of over-thinking this.

I enjoy riding my Ribble and Genesis bikes.I also have an Orbea Gain M20, and earlier for a few years owned a Raleigh Motus.
Bottom line - the non electic bikes serve a very different purpose to that of the Orbea.

When there are hills or a longer ride - then it's the Orbea. But for the joy of riding a relatively lightweight road bike - then it's the other two. Your Dad may well have a similar attachment to his Whyte bike.

Just get him a electric bike and let him choose which one the will want "on the day".

Oh and he's, lucky to have such a "caring" son. That means more than anything

Thanks for your thoughts, and we had come to the same conclusion of keep the Whyte bike as is and add an electric. He's just waiting for his back to recover and then will try the Carrera Subway e bike mentioned earleir in the thread, Halfords do a 6 hour trial so will give him a good idea never having ridden an e bike before. Will go from there
