I had my own solution to the problem. If the trains can have two locomotives, I can have two hubs. I fitted a cyclotricity 250w (xf07 clone?) throttle only to front of an existing e-bike conversion(yose 350 rear hub pas only) with two separate batteries which work great for now. But I am...

Hi. I have looked closely at your climbs. On the second chart, coming back from the next village, you will be climbing approx 270 feet (130 -400 feet) over a distance of about .6 mile (3168 feet) which works out at a grade of over 8%. Now, I personally have difficulties with such grades as it...

Hi. I took a close look at throttle (FT21X). It has that 3 castled bits protruding about 1 mm spacing but the flexible tapered handgrip end seems to ride up over them and get wedged under the throttle moving part. I might look for a stiff washer here to fit between handgrip and throttle to...

My Yose throttle has become sticky a few times as its fitted next to the handgrip (on left). The rubbery handgrip rides up higher on the handlebars and jams the throttle slightly, as the end is worn and I have occasionally balances the bike against wall with handlebars. So going by...

Plug the charger into the battery. Then use white nail varnish to put a white dot on the plug and a corresponding one on the battery, and this makes plugging in easier and less likely to bend pins.. I have done the same with motor cable.

Hi. It may be possible to change seat post to older style with separate clamp and to fit clamp upside down as shown in photo below. That will reduce saddle height by about 3/4 inch or perhaps a little more. I done this with my daughters bike years ago but it can be a tight squeeze . If I can...

Hmm. Interesting. I wondering if during fitting the tyre, if your turning the tyre on the rim. This can result in creasing the tube at one side of the valve and stretching on the other side. This is easily seen on single wall rims as the valve will be crooked coming out of rim . However, on...

The tube is reinforced and stiff around the valve stem and this can very easily can get caught between the tyre bead and the rim. I would suggest that after fitting tyre and tube to wheel, push the valve stem back in to the wheel to make sure its not caught. Also make sure valve stem is lined up...

Some chargers are not fitted with an earth connection and seem to leak a small amount 220v into the output. I think this is caused by 'stray' or parasitic capacitance in the charger. I have also come across this with cheap replacement laptop chargers...

Hi. I wore down the rear rim on a Pendleton (V brakes) after about 7000 mile of some hilly cycling and had to replace rim. In my case, the front wheel had an identical rim (13g spoke) to the worn rear hub rim and was in good condition, so I used this rim to replace worn rim and stuck a spare...

Sheldon Brown has a good article explaining why a new chain slips on a worn sprocket below. https://www.sheldonbrown.com/chain-wear.html

I had 3 different freewheels making a hammering 'clunking' noise in the last few years. In all cases, a sideways movement can be felt by reaching down onto the freewheel cluster and the wear is evident with a sideways rock.Indeed, in one case (DNP), the freewheel was new so it was not that there...

Hi. I had a Pendleton for a good while and gave it plenty of use before passing it on to another family member. I now have a yose 350 rearkit and there is another bike in the house (mxus xf07 front hub) to compare it to. (all unmodified at 36v)The pendleton is better on hills than the xf07 and...

Hi. When a battery in normally been charged, it will be noted that there is a constant current stage (about 60% of charge) and then a constant voltage stage, which brings the battery up to full charge. Now, from my observations, the problem with cell imbalance is that even if a cell is 0.1 volt...

The mobile phone charger is useful to bring back up the cells with low voltage and can be quicker than draining down all the other cells. I used a 1 amp mobile charger on some of the lower cells but I had to put something in series (12 v 18w lamp) in series to limit the current as the charger...

Hi. I spent a good bit of time investigating a similar problem with a 36v battery. I used a parallel element (5.5 ohm) from a 9 kw electric shower as a dummy load. The cells were similarly out of balance. I observed the following. 1. On charge, the high cells go to 4.25 volts and this stops the...

Hi . I have 2 different (not very expensive) digital multimeters with handbooks and the accuracy spec on the voltage scale in one case is quoted as ((+/- 0.5% ) + (+/- 2 digits)) and the other is quoted as ((+/- 0.5% ) + (+/- 1 digits)). This could amount to an inaccuracy of 0.3 - 0.4 volt when...

Hi. I have similar situations with battery and often carry additional batteries connected via diodes for long journeys. In one situation, I have a small but strong pannier in which I can carry additional batteries. In another case, I have used the strong curved plastic from a container and...
