Another throttle question to ask ????????

[mountainsport]

Hello to all,

When i had purchased my first ever electric bike and also being a true novice to the game,i was told not to use the throttle continuously for two reasons,one it will decrease your range and two there is a great possibility in damaging the throttle.

I do know for sure that the first part of the advice is 100% true about range loss,but the second part of the advice i'm not too sure in what to think. The question is by using the throttle 24/7 without the aid of using the pedals,can this cause any damage to the bike in any possible way electrically.

I don't think so, no.. but I can perhaps see what the person was getting at... if you have one of those thumb throttles they tend to break after a while as they're not very well made or strong.. so I guess with more regular/daily use that could happen..however it's not really an issue since they're so cheap and easy to replace eh.

Whether it puts more strain and wear and tear on the motor using just throttle and not pedalling (and so shortens the life) I honestly couldn't say. I doubt it. But perhaps others who have had e-bikes for longer or understand more about motors and how they work will be able to give a clearer answer.

I would have thought it WOULD shorten the battery life though, because you're going to be running the battery empty much quicker and so needing more frequent charge cycles. Since the battery is the most expensive thing to replace on an e-bike I can see the logic in trying to avoid riding only on throttle all the time and extending battery life by pedaling more.

From a standing start applying the throttle would put heavy loading on motor, which I try to avoid, and only apply throttle to maintain momentum while taking a respite from peddling

There's nothing in the throttle that can wear out by use unless you have one of the not very common Magura throttles that have a potentiometer rather than a hall sensor. I've broken two twist-drip throttles when I was going up a hill at full throttle. On each occasion I hit a bump, which caused me to pull the twist-grip more than normal, which then broke the rather weak magnet holder against the stop. They were then both permanently stuck at half-throttle because that will be the state of the hall sensor without magnets. That's one reason why brake cut-offs are important.

If you have a look inside the throttle, you'll see that it's only made of thin weak plastic. It's nothing like a motorbike throttle.

I have used my "thumb" throttle only for the last 4000 miles and 3 years on my Brompton. Its been fine and faultless. In the end though I got fed up with holding it down so I fitted cruise control, with a cut out brake of course

I use lower powered Tongxin motors so always pedal before applying throttle and most of the time always assist the motor pedaling as well.

I am torn between pedelec and throttle, both have their advantages/disadvantages. When the weather improves I am going to fit my other Brompton out with pedelec, throttle and three position power switch. Not sure how I am going to find an umbilical chord connector for that many wires/connections though

As an aside when you do that do you use the same connections to the controller for throttle and pedelec as I think my lyen controller only has one set of throttle/pedelec connections ?

My Brompton Nano is throttle only.

I was told I could have a pedelec control as well, but decided against it on the grounds of avoiding clutter on the bars.

Not sure now if it was the right decision.

I do sometimes get fed up of holding the throttle open, and it's on the right which makes signalling and turning more complicated.

The throttle can also be a blunt instrument, I reckon leaving an ebike on a lowish pedelec mode is more economical on power.

 

[jerrysimon]

Rob your throttle is a twist grip throttle right ?

Cruise control helps though you would need a thumb throttle and cutout brake. Probably a new controller as well.

If I could only have one on my Brompton it would be a throttle.

BTW Rob Nano is a Tongxin motor but I guess you know that right ?

If you're getting fed up holding open thumb throttles, just take the return spring out - works a charm on my bike I did that instead of fitting cruise control.

Ofc, you should have at least one brake cut out if you do this!

Yes, twist grip throttle with the traffic light battery indicator.

I wasn't aware of the make of the motor, I just asked Nano to convert the bike.

The motor is doing the job, runs almost silently.

All I've had to do is tighten the circle of screws on the casing, a bit of oil spun out which I took as a hint.

Range is not dependent on the throttle or even the PAS, it is totally dependent on the rider and how much effort is also put in alongside the motor power.

You can, not pedal with a throttle and also not apply any assist but merely turn the pedals to provide all the power via the PAS.

To extend range you simply release the throttle and ride the bike normally, with the PAS it needs to be turned on and off via a switch (which has a limited life span dependent on the number of transitions).

I would favour the display switch panel failing first if maximizing range riding style is used.

Standard systems operating within their design parameters should be able to cope with a degree of no rider input but both setups can be stressed electrically by heat and over current but the controller/battery protection should trip in to prevent damage.

Yes the Tongxin motors are very nice and very suited to our small wheeled bikes. Worth checking those screws as you say. The forward motion of the wheel tends to tighten the casing anyway.

If you are interested how it is put together take a look at these pics.

Thanks Jerry.

I've had a look at the pics, not my area of expertise although I did once change the brushes on a Lucas dynamo.

Or perhaps it was a starter motor - can't remember.

I supervised (made the tea) during the installation of my Nano.

Looked quite straightforward, the forks were spread a tiny bit and the dropouts widened a bit with a file.

Slightly wary of that, but it's bolted together solidly enough.

Do you know what's happening with the factory Brompton e-bike?

Last I heard it had been delayed after a supplier went out of business.

 

[jerrysimon]

Yes its been put back but not cancelled so I have been told.

They invited me down to the factory last year to speak with the Ebrompton designers and look at my super light conversion with the even smaller 1.4kg Tongxin Goldant motor fitted in pedelec form to my M2LX.

However they subsequently pulled the invite when they had problem sourcing their motor. Very disappointing

Best way to maximise range I've found - Only ride on the level & downhill; so.....

Anyone know where I can get a Moebius Map?.... Or do I need an Escher one?

 

[Old_Dave]

Just look from a different vantage point.... It's can be all down hill

Dear shemozzle999,

That was well said,i repeat, Said well was that.

Mountainsport. IS IT REALLY TRUE THEN,THAT ALL THINGS SHOULD BE DONE IN MODERATION?
