Actually Riding the Sondors Ebike

Yes mentioned, but that is all it was, words.
Adding PAS is not cheap. It is also best done while the bike is in production as oppose to post production.
In my opinion, "torque" sensing is the best as compared to cadence sensing. The cheapest system I have seen are about $150 and I don't know if they fit Fat bikes.

Storm added pedal assist a couple of months ago:

Pedal Assist: All Sondors eBikes will have a pedal assist feature included. Pedal Assist ensures easy start if you choose pedals instead of electric power. Also adds another pleasant way to ride the bike with extra help from battery and motor. In Storm’s words:

“I enjoyed this new feature very much and hope everyone else will appreciate it also.”

George, is there any indication whatsoever that Sondors bikes are equipped with PAS? If there is I stand corrected and apologize.

I also did not see anything in the instruction video to indicate this.

PAS is definitely on the bike, enabled from the factory. Sorry, Hurley.

Nothing to be sorry about. I am happy for you. How does it work? When you say enabled, what setting is it at? Cadence sensor or torque sensor? Can you vary it?
No computer/LCD meter needed I presume. This makes this bike absolutely even greater value!
 
Radrover utilizes a "cadence sensor" as indicated by the red arrow in the picture below. I am still learning. What exactly tells the motor via peddling and what percentage assist of 350 watts is applied to the motor since you know a lot about it not Sam? I am guessing there is some preset sensor in the rear of the bike or something.

That be the cadence sensor! These are actually relatively inexpensive (I think you could buy the control and sensor from em3ev for less than $30-40), at volume manufacturing pricing I doubt they added much more than $10/bike if that. Also, if you know how to wire to the controller they aren't particularly difficult to install from what I have read/seen.

I'm thinking I'll probably pull the throttle off my radrover entirely - not going to use it and the pedal assist is pretty beefy. Level 1 limits the motor to under 500w but all other levels are unlimited - I'm pretty sure the radrover is bursting upwards of 1kw, definitely breaking 750 when accelerating but quickly receding to a couple hundred watts at speed. Love having the display with the watt usage on the radrover, bet you could add one to the sondors bike if someone wanted to.
 
Talk is cheap(no pun intended). Do you mind providing a link? A cadence sensor has to be tied into the specific controller as far as I know.
Why doesn't Prodeco and other companies do this if it is only $40? Why are Prodeco folks opting for a $150 add on?

Congrats on the RadRover. I think that bike is exceptional value. Especially for the first funders.

$35. Prodeco chooses to charge $150 for the same reason there are $4-6K electric bikes, because some people will pay.
 
Wow. This is awesome! This actually works with any 36 volt or 48 volt controller? I will link this to the Prodeco folks. Even if it is not as responsive at least you have level adjust. The $150 torque sensor I tried seemed sorta all or nothing. Thx

At factory level cadence sensor is $15 a piece. I have heard it from folks at the Interbike. I am not mentioning the names to respect privacy.
 
You'd probably want to ask Paul at em3ev what controller(s) it would work with first, I was just pointing out that there are inexpensive options.
 
I think you can add a pedal assist for very low numbers. Just search for "sensor pedal assist" if you want to try to find the specific one. This one is 2 dollars and change (and it is on sale.) I think 12 magnets is a good number, but I don't deal in the black arts of pedal assist. Twelve magnets runs 10 or so.

The lesson of the Sondors bike, even the RadRover, is that these are Chinese rules.
 
The bike does have PAS.. Read the updates on the IGG Sondors website, from 2 months ago.. They also went with Tektro brakes and they upgraded to Samsung batteries.

The bike has had many other upgrades.. The 90 minute charging time was for the new owners getting a mostly charged battery from the factory.. Actual charge time from a drained battery should be around 4 hours.
 
agreed on all but the claimed charge time JoePah, there were no caveats on the claimed charge time. Sondors got it wrong.
 
I'm curious... All those in this thread who have actually ridden a Sondors, please raise their hand.

*crickets*


So uh... what's with all the chatter in this thread? This forum is really fairly amusing.
 
Point taken Not Sam, I tried to stay out of this thread and forgot myself.. I really did want to see what people thought of their bikes.. I shall try to observe only for a while :)

Your pricing is off folks . What you're listing as $30-$40 is just the 6 or 12 magnet sensor on the crank--doesn't include all the wiring harness, controller or new console if the pedal assist has levels to choose from. A super simplistic system with no level options, just on or off, would be less expensive, but still more than $30 and doesn't ride well.
 
The IGG page is finally showing some sales, maybe 10 in the last 24 hours. So, basically, if they can find a way to offer the bike without inventory, that's interesting. Collect orders and make bikes every few months. I don't know if this is the plan. It's awkward with the lawsuit and all that stuff, but the bike, by itself, seems OK. If they can offer them and get people to accept the terms, it seems to change the low end of the market, for a while. It just seems like eventually the regulatory and liability things will catch up with them. It's not a developmental campaign, it's now a storefront.
