Controls for roadbike drop bars

[Rt3005]

I was wondering if the basic hub motor kits can be adapted or fitted with controls that actually fit on road bike handlebars?

Think the bars are thicker aren't they? In which case the Display could fit on an extension mount. Brake switches are a problem with drop bar brake/changer levers. You can fit an in line switch (the brake cable runs through it and the switch senses the motion) you only need one.
If it's a carbon frame then it may be a non-starter as the drop outs wouldn't take the torque.

Its an aluminium SAB frame.

Most drop bike have 32mm dia bars so some displays will fit centrally as they utilise the 32mm central fitting of mtb or hybrid bikes. The issue arises with displays that use a 22mm bar fitting for the remote selection pad like the Kt LCD3, 8 or 10 would fit as will a tongsheng vlcd5 as they both sit centrally, the intelligent displays with lishui kits will also fit.

Tbh drop bikes with the full 32mm bar are not very suitable for conversion with display unless a 22mm - 32mm mount adapter can be 3D'd.

I use a friction drive on my gravel bike, it is simple and with no display.

Any simple and cheap way of adapting the brake sensors on standard flat bar brake levers to work on a road/gravel bike type brake lever? I have a spare set of standard ebike brake levers anyone modified basic road brake levers to accept them? The road brake levers I have in mind are not brifters they are purely basic brake levers I'm planning to use a separate shifter on the bike but would like to have brake cut off working on both levers. I know some people have just used throttle only on road/gravel bikes so no brake cut off is necessary but I would like to keep the bike a completely legal pedelec gravel bike. I guess if the throttle only works when the crank is turning that is completely legal but still I like the idea of working brake cut offs.

For cable levers a simple fit should be HWBS fitted inline.
Trying to adapt std cutoff brakes for drops isn't practice or possible, the other obvious is to use the sensor/magnet combo as used for hdb's where the magnet is simply moved away form the sensor.

Yes that seems to be the only way I've seen it done and realise the important thing is it needs to be reliable but I still wonder if there are other solutions perhaps on dual pivot brake mechanism you could mount a small bracket by the brake quick release that angled the button against the arm of the caliper and when the brake mechanism is used the pressure on the switch is released. It feels like their should be an easy way of doing this but I guess it comes down to reliability, you can probably make something work quite easily but how long will it stay working.
