Adding a throttle

[teskow]

I have a Brose powered mid-drive bike coming and am wondering if anyone knows if it will be possible to add a throttle to it?

 

[Deacon Blues]

It's not possible.

 

[Merle Nelson]

That's not the answer I would want to hear if I were asking.

 

[LimboJim]

The Big 4 "mainstream" motors - Bosch, Brose, Shimano, Yamaha - are all designed for pedal assist use only.

A crafty electrician/engineer MIGHT be able to find a way to add a throttle to them, but given the cost of replacing those motors if things went south, I wouldn't try it...

 

[teskow]

Oh well, it didn't hurt to ask.
I have a bike with a thumb throttle now that I don't use often, but when I do it is appreciated. For intersections and topping a hill it is the cat's meow.

If you're a DIY'er, a PAS to throttle converter can be wired up:

Simple PAS to throttle converter using an Arduino Nano

The heading says it all. Solder according to the schematic and program the Arduino using attached program (adjust as needed, defaults work well for me). Should work instantly. You can put the Arduino Nano inside the controller case (insulate using shrinking plastic), in that case connect the...

a mid drive makes it unneeded. as soon as you strew on the peddle you're going the motor is working.

I believe that is true of all bikes with a torque sensing system, mid or hub drive. It is on my Juiced RipCurrent (hub drive) if in the torque sensing mode.
I do like the throttle for starting from a stop as I can do so with both feet on the ground and not have to do any shifting while in the intersection.
Can I live without it, sure. Would I rather have a throttle too, absolutely.

if you dont learn to shift on your new bike your going to have issues and your chain will not last.

Just what is it you think I don't know how to shift a bike fooferdoggie?
Been shifting most of my life and think I am pretty darn good at it too. If I don't know how to do it at 82 years old I suspect I never will.
There is a time and a place for a throttle and I like having one....

I was just talking about not shifting when you plan on stopping. you would not want to use a throttle if you forget to shift on a mid drive either thats going to chew the chain up fast.

if in the torque sensing mode.

You cannot change the mode on a proper Euro mid-drive motor e-bike.

Interestingly, my e-gravel bike, with a Bosch gen 4 motor, weighs only 39 pounds and I've never felt the need for a throttle on this bike. On the other hand, my Watt Wagons UC Pro, which weighs a portly 65 pounds, and is physically much larger, is much more difficult to get moving from a standstill. Maybe it's the difference in the torque sensing between each of the motors. The Bosch gen 4 torque comes on almost instantaneously, while the Bafang Ultra motor takes slightly longer to engage. It's also harder to get the much heavier/larger WW bike moving.
The end result is I've never needed a throttle on the lighter Bosch powered bike, but I wouldn't want to do without a throttle on my big, heavy UC Pro.

Different spokes for different folks!

I have popped wheelies on my Bosch bike even with the gen two speed the nI feel good can can put out 600 or more watts starting out.

I took my new Hydra out for the third long ride today. I have just been using ECO pedal asist 2 and 3 to ride and get used to it. Well I bumbed it up to Sport ???, and then 5. I was popping the front wheel off the ground without trying. It was so effortless and I wasn't skilled enough to control it yet and I'm just busting up.

I then set my foot against the pedal to rest it as I told my wife why I was laughing and instant wheelie. Stopped it by brake tap......and turned it back to ECO 2.

Maybe check sport mode till you adjust the settings.

a mid drive motor means that the pedals still need to be moving since the wheel is chain driven and the motor is connected to the crankset. throttles are common on hub motors since the motor is already in the wheel.
I got very used to a throttle start up when a light turned green on my old bike. on a mid drive I've never needed it, even starting on a hill.

 

[Deacon Blues]

@Merle Nelson, I'm still waiting for Pushkar to ship my Hydra.
What range are you getting from your Hydra battery?
The range on my UC Pro has been better than I thought it would be. A couple of days ago I did a long ride (107km) and at the 70km point I swapped out my battery (bike came with two). I still had 41% left, and may have been able to to the remaining 37km with the same battery, but I decided to play it safe and switch.

 

[Merle Nelson]

I wouldn't have good info on that. Most of our rides are 10 or 12 miles but only half of it is up most of the time - coast down. We did do 20 miles one time, 10 up. Batt had about 15% left when we got back.

Oh, did 22 or 24 with BarnBoy one time - about 1/3 coasting down. Batt was as low as you want to take it on that trip.
