Seastan Posted January 22, 2018 Share Posted January 22, 2018 I've owned my MiniPro for three months now, riding it about 5 days a week. I ride it to and from work each day, which is 2 miles there and 2 miles back over flat terrain. When I get back home (after 4 miles) I've got one bar left of the battery, and will have actually been at that level for the last half-mile of my commute with reduced speed. I suspect I could go maybe 1 more mile on the battery before it died. Next time I go out I'll try to get a screenshot from the ninebot app confirming the exact battery %. Since it does get me to work and back each day (which is why I got it) I haven't felt the need to complain. I just assumed that advertised range of 14 miles by ninebot was some hypothetical maximum achieved by a 80-pound person going downhill in a vacuum, and being a 190-pound person I should expect less range. But this seems like a lot less. But looking around on the internet is seems that other people of comparable weight are going up and down hills and still getting a much further range out of their miniPro. So what gives? Should I file a warranty claim for a faulty battery, or is this to be expected? I have tried out the charger from More4Mini and it does get me maybe a mile extra range, enough so that I'm not stuck at a reduced speed for a chunk of my commute. But if there is something wrong with my battery, I'd like to know. Quote Link to comment Share on other sites More sharing options...

Hopefully one of our MiniPro experts will chime in here. Quote Link to comment Share on other sites More sharing options...
Vik's Posted January 22, 2018 Share Posted January 22, 2018 @Seastan Sounds like a bad battery/cells. 4 miles is not even in the ballpark of what it should be. With the normal EU-type adapter (63v, or More4Mini one), you should get around 20 miles in warm weather. There were quite a few reports about DOA MiniPro batteries lately so chances that you've got a lemon are pretty high. Quote Link to comment Share on other sites More sharing options...
icom Posted January 22, 2018 Share Posted January 22, 2018 a few thoughts: batteries get less useful over time, but 4 miles at 3 months is too fast My minipro has been my daily commuter for over 1 year (190lb ), and I'm probably at 6-8 miles for realistic use. I've heard people mention if you like to fast accelerate, you'll eat more power. the battery gauge is not always entirely accurate. it seems to burn down faster after continuous rides. sometimes I'll be at 1 bar, then many hours later when powering it up and using it later, it'll go to 2 or 3.

Seastan Posted January 22, 2018 Author Share Posted January 22, 2018 Thanks for the replies so far. I have some screenshots of my commute this morning: Fully charged: After 3.8 km: 44 minutes ago, icom said: batteries get less useful over time, but 4 miles at 3 months is too fast I do recall getting a bit better range the first week I had it - maybe 6 miles with the stock charger? I recall it going completely dead in the middle of a longer commute I made in that first week, around the 5 mile mark. Though part of that commute was uphill.

That's some drastic remaining mileage drop after just 3.8 km and 15 minutes ride! A am getting around 30 km/19 miles stated mileage and got more than 32km real range last summer (at +25C): Quote Link to comment Share on other sites More sharing options...
FreeRide Posted January 23, 2018 Share Posted January 23, 2018 What was the temperture during that last recorded trip? And show the battery info screen at the start. Certainly with the 63V charger you should be getting more than 4-5 miles, but maybe not if it is cold. Also what is your tire pressure?

FreeRide Posted January 23, 2018 Share Posted January 23, 2018 (edited) As a data point. This weekend at about 40°F, i got 9.1km with 37%/2137mAh remaining on basically flat trip with 1 good hill. I started with 87%/4977mAh capacity. Battery started at 16°C and ended at 19°C. This is probably typical for me, hard to say since i didn't start with a full battery as i normally would. If the mileage shown on yours is all that has been done on that battery, then it seems to be underperforming, but i would not rule out tire pressure.

Good point with the tire pressure though as all of mine MiniPro's were delivered to me with too low tire pressure.

I don't have a pressure gauge but I checked them with my hands and they feel pretty low. I'll pump them up and see if it helps any. Thanks for the tip! Unsure if it will double my expected range though... The coldest temperatures I ride in are around 10 C. Quote Link to comment Share on other sites More sharing options...

If you can feel the tires with your hands as low (slightly squishy), then they're REALLY low. Wouldn't surprise me if they're in the 15-20 psi range. That will absolutely TANK your mileage. As icom stated, pump them to 45 PSI. Edited January 24, 2018 by WilliamG Quote Link to comment Share on other sites More sharing options...

I just checked with a pressure gauge and as you suspected, my air pressure was INSANELY low, like 10 psi low. I feel really dumb for not thinking to check this, but I guess the pressure must have been that low when I received the miniPRO and I just assumed they came properly filled. I pumped them up to 45 psi this morning and rode it to work, and WOW. It's like I have a whole new device. Faster acceleration/stopping, and it also fixed an annoying clicking noise I was getting with the right wheel. But most of all the range - I burned only 10% of my battery over the 2 mile commute. Which is about 5 times better range than what I was getting before. Crazy, but when I think about how much harder riding a bike is with flat tires, it makes sense. I guess I will cancel that warranty claim I sent in to Segway... 2 Quote Link to comment Share on other sites More sharing options...
WilliamG Posted January 24, 2018 Share Posted January 24, 2018 YAY! Glad to hear that solved your issue. 10 psi is... wow... insane. I always check my pressures before every ride. Because these are tubeless, a little air will always be escaping as the seal is between the tire and the metal only. Enjoy riding! Quote Link to comment Share on other sites More sharing options...
icom Posted January 24, 2018 Share Posted January 24, 2018 I can't imagine what riding around at 10 psi feels like. wouldn't you be riding almost tire against metal.. Quote Link to comment Share on other sites More sharing options...
icom Posted January 24, 2018 Share Posted January 24, 2018 another tip.. I use my minipro as a daily commuter, I check tire pressure every 2 weeks, tend to lose around 3-5 psi i used to do 1x weekly, but you really don't need to. Quote Link to comment Share on other sites More sharing options...

Yep, I also suspect it's the reason I lost all my red screw covers within the first week, because the flattened tire must have popped them off. 1 hour ago, icom said: another tip..

FreeRide Posted January 25, 2018 Share Posted January 25, 2018 Nice to have it all solved. My tires keep their pressure pretty well, i can't remember if i used green-goo or not, but i might have. Quote Link to comment Share on other sites More sharing options...

I am checking the tire pressure like once in a couple of month and they keep the pressure alright. Quote Link to comment Share on other sites More sharing options...
Segway Sam Posted October 25, 2018 Share Posted October 25, 2018 (edited) I routinely get 17 miles range when riding on fairly level Terrain, and because I am 6'4" and 280 + lb when I go over incline's or hilly Terrain my mileage decreases dramatically I've owned mine now for 3 weeks and was only getting around 10 miles per charge one thing I did to increase my range was to inflate the tires to 65 PSI I do not recommend this as Tire failure may occur so try this at your own risk, it works for me the ride is somewhat rough but the benefit of the extended range outweighs the drawbacks in my opinion I only have 57 miles on it will keep you informed about my range as my total mileage increases Edited October 25, 2018 by Segway Sam Added content Quote Link to comment Share on other sites More sharing options...
Matthew Hagar Posted September 25, 2023 Share Posted September 25, 2023 I can't even get my minipro0993 to pair to the Segway app or my phone and it seems like the person before me put it in a mode I can't go to fast before it leans back and makes me slow down before it leaves out again Quote Link to comment Share on other sites More sharing options...
