Can't say I've noticed this problem, but then I tend to take advantage of gravity to freewheel down slopes! Does stopping pedalling for, say, a couple of seconds just before you reach the upslope make any difference? Just wondering if there is some sort of PAS lag caused by the higher speed...

I read a recommendation somewhere on t'internet that 90% EP90 gear oil mixed with 10% sewing machine oil is a good mix for bike chains. I thought I had some EP90 in the garage but only have 20w/50 mineral engine oil. I'm too much of a tightwad to buy both EP90 and sewing machine oil just to try...

You're not supposed to "hit it with a mallet"! 1mm is way too big. Seat posts come with the size stamped on them. If you don't have the original seat post get a digital caliper and measure the seat tube to get the right size. I do hope this isn't another bike that you intend to sell on. If it...

Couldn't even be bothered with any pretence by fitting a chain!

Maybe it's the wrong colour, or it's just plain ugly. After nearly fifty years I've come to realise that the more I second guess how to please my beloved, the less successful l am. Females just think differently and expect us mere males to know. There should be a health warning about it on...

Have you tried setting C14 to 3? In the Chinglish instructions this is 'assist strength of intelligent pedal motor". My KT's came set on 2 (of 3 levels). I tried setting 1 out of curiosity and it gives a slow ramp-up which I guess would be useful in being more gentle on nylon gears when using...

You can buy the "350w" 18amp controller from Yosepower to use with your 250w motor. They are available integrated into the battery slider or "stand alone". It is much better than the 15 amp YJT controller supplied in the 250w kits. If you also want to unlock the speed limit and have a full...

I can concur. I just had to try my recently acquired 48v. battery (bought for my hybrid fitted with a Yosepower 250w. cassette motor) on my Yosepower 350w. freewheel motored "winter bike". Flippin' awesome at 15amps - no need for anything higher from the 20A KT controller. By far the best...

It's 18 mm on the rear hubs.

As you appear to be running a business, do you have public liability insurance? Does your battery repairer? Bear mind that any decent insurer will ask you to declare your competences (qualifications and experience). In the event of a claim, if you can't prove that you operated within them you...

Out of curiosity I've just made up a test lead using a jack from an old charger wired to a connector block. I have two Yosepower 36v 13Ah Hailong HL1 batteries and a PSWpower 48v 15Ah Hailong G70 battery. In all cases the charging socket is live whether the battery switch is off or on. One of...

By coincidence I've just got back from an 18 mile test ride on my hybrid that has a Yose 250w AKM95 RX cassette motor and a newly fitted 20a KT controller from PSW power. I've run it at 15a with a new 48v. battery and the performance is superb in every way. Steep hills are flattened with PAS...

I use XT60 connectors. You can get black ones if you want a stealthy look:- https://a.aliexpress.com/_EucorMm I also ordered a couple of metres of soft silicone sheathed cable at the same time to do three bikes and it was more than enough You'll need some heatshrink and a decent soldering iron...

Have you tried removing the brake disc and spinning it? Perhaps the disc bolts are too long and catching the motor inside?

I tried to buy a battery using PSW's website, and managed to navigate to the checkout where there was a message to the effect that "we cannot ship to the UK". I fired off a disgruntled email asking if that is the case, why do you list it in UK pounds?. I got a very quick and polite reply with a...

If you buy a KT controller from PSW you can because they have a 9 pin connector for the 1T5 cable. KT controllers listed by Topbikekit only have an 8 pin connector so they will only take 1T2 or 1T4 cables. This is why it is much easier to buy the controller, display, cable, throttle, brake...

There seems to be some confusion here. A motor usually has a 9 pin waterproof male plug on the cable that connects to a 9-pin female connector cable going to the controller. There are 3 types of cable to connect other items to the controller via another (but different) 8 or 9 pin waterproof...

Before going to the trouble of changing handlebars, are your wrists angled down when you grip the bars? If so, try rotating the brake levers down to encourage you to keep your wrists straight. I found that bar ends gave an alternative position to move the hands occasionally and relieve any...

On a slightly related topic, I have a dilemma that I'm struggling to understand. When I switch my Yosepower 36v.13A batteries off the reading at the discharge socket is zero - as I would expect. My newly purchased PSWPower 48v. 15A battery charges to 54.3v., which I consider to be OK. However...

Not really. When I set out on this EPAC malarkey I was concerned about making it stealthy to avoid theft. The first iterations of this bike had the battery on the rear rack only and with one of those "waterproof" Hailong battery covers and panniers fitted it made a passable impression of a...
