    bike gets away from me. Is there a product that could help me?

    I have a Pedego Interceptor. It has pedal assist and a full throttle. By mistake, I have been walking my bike and by accident I twisted the full throttle. I had the pedal assist in 1 so the full throttle was operable. My bike took off. The problem is me - not the bike. Is there a mechanism that goes between the handlebar grips and the throttle that would prevent my hand from slipping on to the full throttle when I am walking the bike --- just in case there is a time in the future when I fail to move the pedal assist to 0 before I start walking my bike. I hope this makes sense.

    If your Pedego has a simple mechanical type brake switch, then you could wire a hard switch inline. Maybe an SPST, water-proof, mini-toggle switch on the bar. Flick it on, and it would close the circuit, making the bike think you have applied the brake. That should keep the motor off, even if you hit the throttle. Get on, and flip the switch back to off, so that the brake sensor functions normally.

      That's an excellent suggestion. However, if the rider remembers to turn the toggle switch on/off, it would be similar to remembering to move the assist down to level 0. Another thought would be swapping the twist throttle for a thumb throttle which is more difficult to accidentally activate. Of course, if you don't like a thumb-type throttle, that's a non-starter.

        Point taken Fred, but I think chrisblis is suggesting that the setting on the controller is something that can sort of hide, but a switch would be very visible. A second option could be a momentary push button or rocker that is held down only when the bike is walked.

          I have a BikTrix Juggernaut Ultra FS, And removed the throttle, brake cut off switches, and shift sensor cut off switch. I mainly took the throttle off not from bumping into it accidentally, but because I never used it. I took the brake cut off switches off because when riding technical trails, I often drag the brakes through corners while still peddling. The brakes will always override the PAS, and helps me keep my balance and momentum. I took off the shift sensor because it was a bit sporadic, and when working, would cut the power off way too long after shifting, so I manually ease up and let the motor completely cut off, then shift, then start peddling again. The bike works so well under PAS, I saw no real reason to have a throttle, especially a thumb throttle, which worked more like an on off switch rather than a liniar throttle, so had no use for any of the cut off sensors.

            I'm speculating that the OP is walking the bike with the system in "walk" mode or very low power...? If not why not just have the power switch off?

            But if walking is and has to be under power... a quote from my build thread.

            "My other thought after doing a couple burn-outs and running over my foot once while working on the bike "hot". Was to be able to disable the twist throttle as desired. I accomplished this by using the latch 'on' switch on the throttle assembly, which is originally wired to power the lights on. Removed those wires and put it in series with the throttle 5 volt supply power. Now if I can just remember to disable it when done riding.:-) Considered perhaps using a pressure switch on the seat... but lifting off the seat for maximum pedal power would defeat that... "

            as seen here...

            For me having the throttle power and switch in the same housing worked very well, and was an easy mod.



            The closest I could get to the OP's thought was this...

            Don't know how much lock-down resistance it has... enough to hold a speed setting. But if electronic cruise is not featured on this bike, perhaps a plus.

              Interesting thought on the throttle lock Tommycat. I use an older style, slim throttle lock on my motorcycle. It's just plastic, but holds the throttle well.

              I still think a simple toggle or momentary switch near the throttle is the easiest way to get the result Chrisblis is looking for.

                If he can remember a switch or a throttle lock, why can't he remember to simply turn the bike off?

                One thing I'd suggest is most displays have an auto-shutoff after a timeout period - set that to the minimum so the bike shuts off

                If that' doesn't do it then design and build a "fail-safe" - short of that he'll just have to remember to turn it off... a "fail-safe might be a little circuit that disables the throttle after a very short time of it sitting at no throttle and requiring a button on the opposite grip to re-enable


                This is going to be hard to not sound insulting but if the throttle presents a danger great enough to be concerned with then get rid of it entirely


                I don't consider inadvertent throttle to be a big deal - it's happened to me once or twice... I do have a mental "post-flight" check list that goes something like this:

                Deploy kick stand
                Dismount
                Power off bike
                Power off GPS system
                Power off camera
                Power off sound system

                Double check the check list so far by running my finger over every item again

                Park

                If leaving bike unattended:
                Lock bike
                Remove GPS
                Remove camera
                Remove speaker
                Grab water bottle
                Grab pannier if attached

                Double check the check list so far by running my finger over every item again


                It's been done so many times in that order that it's habit burned into my subconscious so something needs to disrupt that flow for me to leave the bike powered while I'm pushing it (the "Park" step)

                Habit is powerful stuff - create habits the ensure you don't leave yourself in a bad situation.... Checklists are an excellent tool for developing habits... IF this is such a great concern laminate and put the checkist on the bike


                Again, inadvertent throttle is so unusual for me and so inconsequential I don't worry about it beyond my checklist... if it presented what I feel is a real safety concern then I would address it by either getting rid of the throttle (too dangerous) or coming up with a short timeout lockout function or some other function...

                  I really like using a thumb throttle so far. I have a button to set cruise, and using it works great with my cockpit setup/angles. My throttle also has a key, which is a quick/easy way to turn on/off.

                  I actually looked up the interceptor, and it has cruiser bars that result in a throttle position that more forward/back than left/right. Maybe that's the real issue. With that bar angle, I can see how it would be really easy to roll the throttle on while walking the bike, and the controller is on the opposite bar. Shutdown, and power on could be less than convenient to reach, and maybe it takes time for the controller to power up. My throttle and key are on the same side of my MTB style flat bars. So my throttle is harder to accidentally turn, and I can switch on/off instantly.

                  Actually seeing the setup on the Pedego, I can understand the value of a rocker on the throttle side to quickly disable it. Maybe I wouldn't add the switch to the brake signal though. I would interrupt the throttle signal connection.
