Hi new on here with new pedelec

[D8ve]

Hi daves the name just got a ex demo powerbyke salisbury.
one initial question i fully charged the battery and peddeling enought to rase a sweat the power was failing after 16 miles and even though with no drain it lit two batt lights(out of 3) it would fail to drive after 22 miles with about less than 400 m of climbing.
Is the batt shot? compainy recon 27 miles min on flat?

400m of climbing is quite a lot of climbing. Also it only has a 26v battery, so I'd expect about 2/3 the range of a 36v 10AH battery for which my rule of thumb range is 35 miles. Therefore, 22 miles to me sounds about right and compares equally with the Cyclamatic that has a similar battery.

 

[D8ve]

Thanks I going to do a flat loop to day with freshly charged batt. But less than 400 m over 20 miles I thought was almost flat back circa 1 m every 100. In scotland or wales one hill could cover that.
The motor is only 180 watt so it should run for longer than a 250.

And oddly enough a 48v 10ah battery might only give you a 24 mile range.

That claim of 27 miles on your e-bike is something of an exaggeration, common with the suppliers of e-bikes who give idealised figures based on strong light riders in flat still air conditions.

An A to B review and test of your model gave 22 miles as the range on a journey with just two moderate hills nearing the end of the run, so your range is not bad since as an ex-demo bike it's battery might be a year or more old. These lithium batteries do lose capacity with age.

Hi Dave,

Welcome to the forum.

What a pity that you chose that name as an ID

As you will already have realised, we have a d8veh who has been on the forum for long time and I can see this leading to

I would agree with the previous posters on your thread, that is a fair mileage for your bike given the terrain.

Regards,

Hi everyone my run on the flat today was interesting. 10 miles to wickwar with a climb of 40m ave speed 16mph max 24. then battery was struggling. came back over 8 miles and ave speed dropped to around 13 Mph despite max of 24.5. so in total 18.19 miles in 76 mins. i was peddaling strongly at times. maxed out my speed to get 24.5 wouldn't have trusted batt to pull me any where when I got home.
My rought thoughts are 26V by 10.5 A = 273 watt hours. motor rated 180 watts so should last 91 mins. of constant load.
well it was struggling after 40 mins. power assistance dropped despite my pushing the pedals.
Same thing with batt lights on load only empty on off load shows two lights.
Recharge time was around 5 hour mark i didnt keep a close enough eye on it to confirm exact time but that reads 10 amps in at 2 per hour. Loss of effiency and lotts of errors possible on motor and charger batt combo but not on GPS where 1% would be exceptional.

Not the claimed 25to 35 miles with pedaling quoted by far.
perhaps next test should be keep speed to 14mph max and see how long batt lasts or just go back to retailer as batt looks as if its passing 80% down already?

retailer advertised as few months old minimal milage batt cared for. so i expect near enought full Power for the wife to pedal and keep up with me,

Even though the motor is rated at 180 watts it can actually draw a lot more, My Tongxin hubs draw double their rating of 180 watts and that is one of the lowest powered ones out there.

 

[D8ve]

It can draw more but i was often the primary power source as exceeding 16mph. the steep hill was a pair of humpbacked bridges. The range was less than the reported one by A to b in their review of NiMH with a sub 200 watt Batt. in the LPx review on the flat they got circa 30miles.
I have no confidence in the battery or have expectations way to high for the performance of the bike? which is it ?

 

[hech]

Yup I think it probably reasonable to expect 30 miles from a 36v 10ah battery and at 26v you might count on 20miles at least, full power, full tilt. The two 24v hubs Ive tried seemed very wishy washy to me and would gain alot by swapping a 36v battery instead.

Most in here do not get that 30 miles on the LPX Salisbury/Windsor models, a little over 20 miles being common, though I remember one owner reporting 27 miles. There is confusion about the motor rating. Originally it was reported as 180 watts on the website but Powacycle in this forum about three/four years back said that was a mistake on that model and upped it to 250 watts in the website. Now I see they report it as 180 watts again, so difficult to know what the truth is. It has always been recognised as one of the lowest powered ones on the market though.

I have a hub from a Cambridge which Ive been tempted to fit to my bike but just not sure about the power and there are no markings to say which. I cant move down in power living around here with these hills

It's been removed from their range on their website now, but the old webpage is still online and that shows 200 watts. However the rear motor appears to be the same one as the Salisbury/Windsor models which they've variously said to be 180 watts or 250 watts, so difflcult to trust to the figures. In general their full size bikes have been among the lower powered e-bikes and reported as such in reviews.

Motor ratings are pretty meaningless. The number the manufacturer gives is often related more to the controller. I think that Camridge motor will run nicely at 48v and 18 amps. That's about 900w from the battery like I had my Cyclamatic. It looks like the Camridge has the same motor, so you could get it up to 32mph like that, and it climbed pretty well too.

Dave dont tempt me all I want is a proppa bike, I could just over volt the Currie but I want rid of that stupid controller.
