Any new ideas on a throttle with drop bars?

[Lovelock]

Hey guys,

My road bike project has undergone some changes and now looking to properly mount a throttle to the drop bars.

I've googled a ton but haven't found anything yet that looks nice. My current throttle is the thumb throttle but cable tied to the right drop bar.

Has anyone come up with a good way yet of this? Or perhaps a different type of throttle I can buy? A slider perhaps or a simple on / off would probably work for me as I simply use it for a little extra boost.

Thanks.

Grin tech has a little handle bob you can mount one to.

If you are only adding a bit of assist, have you considered simply using a PAS system with different levels of assist instead?

You can check it on ebay, there have many choice for throttle

Here's my solution (pictures below), pretty happy so far but in the near future I will put a hall sensor being operated on my front derailleur lever because I use a bafang with a single chainring. My cable goes inside the bar tape.

You can do a button throttle instead.

Kepler came up with the system first, and I based my 3-button design on his original design. He now is working on a latched-button design that looks more advanced.

If you decide to make the 3-button throttle I designed, be sure to follow all the edits and additional posts I added about it as I learned things and made some adjustments as the design developed. Particularly this post about how to calculate the resistor values.

The as mentioned Handle Bob is the best method I have found for a throttle. As I mainly ride in the hood area It falls readily to thumb and in conjunction with a CA3 and it's cruise control setting is the only way I have to control assist on my two gravel bikes. It allows me to set my own cadence and input to match the assist I want at any given time. I can't stand any cadence sensed type of PAS personally although I do like the torque assist on my TSDZ2 mtb but I still have a throttle on it set for high torque/low speed to help in starting off mainly, especially on steep terrain to get enough pedal stroke in to activate the TA.

I have one on the other side to carry the momentary switch I use for regen, once again just in the right spot to be able to activate it and the brifter at the same time. And a bell, every bike needs a bell.
