LG M36 @ 48.5 grams each as 10s 28p =13.58kg for cells alone + nickle strips + cell holders + bms + case/package = ? (another few kilos). I would think 17Kg is possible.

Nice bike. One important thing to bear in mind (especially with an emtb) is that if you change your rim from 26" to 29" you will increase the motor load by 10%, effectively reducing your 'thrust' or pulling power (especially against winds and on hills) by 10% and the motor may appear to lack...

How about a 69er? i.e. you leave the existing 29 on the front and fit the 26 on the back. This idea was popular a number of years ago and has some advantages and can look well. e.g. link below. https://www.ticycles.com/faq-69er

Hi. I bought a pendleton for my daughter back in late 2017 but ended up using it myself for a good while. I have uploaded the manual below but there are some differences/changes, so I can only describe my one. There are two indications of battery condition. The first is on the 790 handlebar led...

Video below from Justin of grin technologies on geared motor hall replacement might be helpful.

I think the battery was also built into the hub. That made the wheel totally 'wireless' by using the smartphone to control. One idea was that you could change an ordinary bike to an ebike ( or change back) within a minute by simply changing the front wheel on a front wheel version. I think they...

From the photos, its looks like the braking surface of the rims are worn out from v brake. The other wheel could also be badly worn if this the case. Have replaced rims myself. To supply rim and possibly spokes and the tedious job of replacement, I would guess that you would be lucky to get job...

Dont forget that a good athletic cyclist can output well over 250w and up to 400 mechanical watts. It would take over 500 electrical watts to equal this.

Sheldon Brown has a list of freewheel spacing's. But where is says total width, he is really measuring from the sprockets but the list is useful for comparison. https://www.sheldonbrown.com/cribsheet-spacing.html

I have changed the A value to 4, then 8, then 32 at different times, on a 250W 36v TSDZ2 supplied by PSWpower and there is no apparent difference. There is some speculation on endless sphere that this facility has been disabled in the controller (but not in the VLCD5) at the request of some...

I would be cautious about buying anything from the UK at present because of the Brexit difficulties. I have purchased from PSWPower in Germany last March and they have delivered free (with no tax/duty) to Ireland within a little over a week. e.g...

I used a hacksaw to slice about 3 mm off my crank. It was easy enough in my case as the crank was made of aluminium alloy, so was fairly soft. I used a file afterward to clean it up. Took about 20 minutes. You probably need the grinder for a steel crank.

I bought the bike flat packed in its carton from halfords. I prefer to assemble my own bike, which takes less than an hour. The biggest job is getting rid of all the packaging.The manual (if I can remember) comes in a bag tied to the frame along with protective packing etc. The phylion battery...

There is a DIY modification that works with most chargers (e.g 2 wire). It requires a switch and some (e.g 5 amp) silicon diodes and some technical skill. The diodes are placed in series on one power leg by cutting the charger to battery cord and this reduces the voltage. The switch is used to...

I am running this setup for about 2 years/20,000 km and on 3 different bikes. The batteries are charged off the bike so there is a slight spark at plug in. But I never had any trouble with power surges. It simple and just works. The loss is about (point) .4 volts but the reduction in sag more...

Below is picture of my version. The common cathode dual diodes are rated at 20 amp each side, so its adequate for the 15 amp controllers. Its fitted into a 'puncture repair kit' plastic box. The wire need to be clamped well as any movement could brake the legs off the diodes. PS. Diode spec...

They dont have to be close at all. One battery can be fully discharged and the other fully charged. However (and this is very important), this is only the case where each battery individually is capable of supplying full current to the controller. So for example in my case, I often parallel my...

I have used a dual 20 + 20 amp (MBR4045, total 40 amp) as below bolted to a flat piece of aluminium for heat sink (about 2 square inches area) and placed in a small plastic box. Works great at 36 volts. For a 48volt battery, you need something like the MBR 4060 (60 volt) if you want full...

Thanks vfr400 for the tip about C14. In my case, I changed the value to C14=3, and it increased the pas levels (approx) from 60/100/160/245/425 to 80/140/220/300/425. It doesen't seem to effect the PAS5 (maximun power)setting but I think it improves, especially with pas 4, which previously...

It should be possible to measure the 'loss' of magnetism on a motor and then to assess if its a problem or not. That's because a loss of magnetism will weaken the magnetic field and this will reduce the torque and efficiency proportionally. However, field weakening actually makes the motor spin...
