Some observations as I read thru...The bar gauge is base on 48v so if you have a 52v batt you will not hit 4 bars until you get below the 48v range then it's a quick descent to 40v. Battery bonk. I've read about people calling the manufacturer to say they need a battery as theirs is defective...

I'm all for that. I want to prepare factual arguments for not banning e bikes and that is the reason for the probing questions. I don't want these to be in the hands of immature riders or adults whose skills have diminished. I also want designers and retailers to talk about sustained flow rate...

Thank you that bring things into much better focus. Claims are being made about 28 Mph and higher on this forum and how this speed can kill. Road bikes with a seasoned rider are in this range as well. It is important to note 28MPH is with vigorous pedaling and unsustainable for most riders...

So are these run with higher voltage or a 48/52v? What is the "off road " sustained speed? My mosfets burned when we tried to squeeze out higher speeds for more than a momentary burst. You've peaked my interest. Are we talking 50MPH sustained in off road mode? What is the weight of the rider...

So this bike is not pedaled and hits 28MPH with an average rider weighing 200lbs with wind resistance and what looks to be a 3.0 /3.5" tire width at 750 watts in a continuous flow not a burst rate and on level terain? How long can 28MPH be sustained with no pedaling? Color me impressed if that...

I would if it was me...find a friend with a big battery and try it. I suspect you are exceeding the continuous flow rate. If your controller will allow 25A but your continuous flow rating on your battery is 20A you will bonk (tap out) when your BMS says enough. The battery will re balance in...

Are these the 72v or higher battery units with a 3000w hub or higher? I've never encountered anything like that other than reading one time about a 3000w wheel. I know Harley Davidson is working on an E motorcycle but it wont have pedals

I just want to ask...If the bike on the dyno was ridden by a 12 year old who averaged 13MPH on his ride would the police take his bike away because it was capable of going faster even though he was a very responsible, respectful, rider?

What e bike goes 28MPH with a rider on it? just because a marketer claims it does not make it so. What was said above is true . Dyno testing does not apply to real world speed. Are you serious in saying you can de restrict the controller and go faster than 28MPH? Can you touch that speed for a...

I would hope I used my labels correctly. Do you mean ... they (Zen) meant to use KPH? They used MPH in both instances and a 500W at 32 MPH is crazy town. A 500w won't do 32KPH much less 32MPH You would hope marketing people would proof read and or tell the truth. What I find most egregious is...

I've been to the Island many times and it is the last place I would want to ride a bike. I wouldn't want to drive a car there either. In my recollection of Manhattan every other vehicle is a Taxi. E bikes make it easier for people to ride and will attract a percentage of riders who are older...

I agree with everything said above with a few caveats. I would also consider the used market. Some people buy because they have a friend who rides and The bike becomes a coat hanger. I just bought a second E bike for my wife's collection because it was needed in another state on the other side...

Has he never heard of ride services? I'd call uber and ask for a truck. Never tried but I'm sure it would work. Short of that Lowes/Home Depot rent a truck for $25 and everyone has one friend who would help in a pinch, Right? $150? To pick up a bike and rider?

750W rear hubs must have made a significant increase in efficiency. With my 20AH battery at 52V on a flat surface hammering the throttle and pushing a big gear 52/13 with a fat tire 26/4.0 I can get to 28KPH not MPH. That is with a 1500 watt hub. The tire on the zen looks to be 3.0 or 3.5? Was...

Clearly one of the most important aspects of the above story is the braking power of the e bike conversion. People who lack knowledge of physics have no business doing a bike build. The advent of the disc brake is extremely important for an e bike.. I have an issue with some of the focus stats...

Perhaps the bike is in Alaska for snow or in Cali for beach patrol. I can speak from experience a fat tire eats a 20AH battery with a 25A continuous draw for lunch. You need a continuous draw in the 40+ and a burst draw of 50A. Mine would tap out after 5-10 minutes when pedaling if I asked...

Wow 60AH! I went from 20AH to 36AH due to the rolling resistance of my fat tire causing battery bonk when climbing. I've been riding for 50+ years and have carpo tunnel type problems when riding now. I loved drop bars as I could ride my brake hoods and tops and the drops to avoid numbness...

The airline I flew (Allegiant) considered my e bike baggage and flew it for $50.00. Has to weigh under 50 lbs and I sent my battery separate. bike has to be in a box. As I recall bike flights was around $150.00 for the same bike. Call the airline. Once you ship the battery it's a regular bike...

I wonder if a group of you with a motorcycle licenses started riding in the road with proper equipment (turn signals, horn) at 10 mph and blocked a busy commute if they would start to get it. Ride right next to the bike lane your not allowed to use by their law. Do it every day for a month but...
