Quoting from https://www.gov.uk/electric-bike-rules#:~:text=You%20can%20ride%20an%20electric,be%20registered%2C%20taxed%20or%20insured

Quote from: His Majesty of BikesElectric bikes: licensing, tax and insurance
You can ride an electric bike if you?re 14 or over, as long as it meets certain requirements.
These electric bikes are known as ?electrically assisted pedal cycles? (EAPCs). You do not need a licence to ride one and it does not need to be registered, taxed or insured.
What counts as an EAPC
An EAPC must have pedals that can be used to propel it.
It must show either:

• the power output
• the manufacturer of the motor

It must also show either:

• the battery?s voltage
• the maximum speed of the bike

Its electric motor:

• must have a maximum power output of 250 watts
• should not be able to propel the bike when it?s travelling more than 15.5mph

An EAPC can have more than 2 wheels (for example, a tricycle).

What's not clear is what "it" means, as in "It must show either:" and "It must also show:"
Is "it" a sticker or something? Maybe a console display?

And:

QuoteOther kinds of electric bike
Any electric bike that does not meet the EAPC rules is classed as a motorcycle or moped and needs to be registered and taxed. You?ll need a driving licence to ride one and you must wear a crash helmet.

Whatever ... I would interpret all that to mean that with the throttle, the 750 W motor (is there a 500 W limit governor?), and the top powered speed of 32 km/h, you are hosed. It seems to me that it would be deemed to be an "electric motorcycle".

Update ...
I powered it up yesterday to check the wheel size setting and noticed that all segments were displaying properly. Then I (did something?) and saw that they were back to looking like the photo.


I decided to see if I could open it up and see what's what, but I could only get as far as removing the black plastic bezel.

Here ya go - "sissy bar"!


When I were a lad outgrowing my 24" single-speed with coaster brakes, I put one of these on it and found that I could climb hills while carrying a bag of groceries in one arm and steering with the other.
It's a bit tricky to mount unless it's on a step-through frame.

I'm on the lookout for a front & rear set of lights, but in the meantime I bought these Husqvarna "Classic Work Gloves" to make my hand signals more visible. The grey logo and wavy wrist stripe are retro-reflective. They're quite comfortable with a decent grip and a breathable fabric.



I give my fingers a wiggle then point steadily.
If I ever do install some turn signals I'll still be wearing these for protection.

About the right-turn hand signal made with the left arm - I'm pretty sure that originated in the very early days of automobiles when they didn't have blinky lights (or flags that flip out = "Trafficators"). Either the cab or a passenger on the right would obscure one made with the right arm.



I imagine they are still legit to use in a car temporarily if you discover that you have a faulty signal lamp.

Thanks!  I didnt know (or dont think) that I could change my wattage?  The hidden menu in my controller only has, 1. tire size, 2. Top Speed, 3.3 KMH/MPH.

Am I missing another secret menu?

On my RadMini ST2 it goes:
1 wheel diameter
2 speed limit
3 display backlighting brightness level
4 speedometer display units metric vs imperial

I would think a hose would be fine if you reduce the pressure. Put an inline cutoff valve just upstream of a pistol-grip nozzle to control the flow.



Covering the electronics still sounds like a good idea though.

What if you just shift it up to the highest gear to get a bit more slack? Can't you then get the bottom of the derailleur submerged in a container of solvent?
Or use a narrow rectangular pan to get a longer section of the chain submerged, slowly turn the pedal by hand, and work it with a brush.

I suspect that my speedometer/odometer s calibrated for a 26" wheel. How would I adjust it to my 20" fat tire rim

For this style of display and separate PAS control with three buttons, press MODE to turn it on, press and hold UP and DOWN buttons simultaneously to get to the settings menu. The first setting is for tire diameter. Press UP to increase, or DOWN to decrease. Press MODE [and hold?] to save and exit.

Well, thanks for all that.
I wonder if latex tubes influenced the adoption of nitrogen for filling tires. Larger molecules being slower to leak through, and non-oxidizing.

QuoteFor my Radmission, I've ordered tubes that just say "butyl."

What about "May or may not contain nuts"? 

Quote from: JimInPT on January 22, 2023, 07:53:49 AMUnlocking my MiniST2's top speed was one of the very first mods I did and aside from making the bike a little bit better hasn't changed anything.

I have a RadMini ST2 (2020) and I was able get to the menu and change the setting from 32 to 40 km/h. However, on my test drive the next day (level paved road, teeny bit of tailwind, full twist throttle), the top speed I could get was about 34 km/h.
Whee!

I double-checked the setting afterwards just to confirm that it did not somehow reset to 32 after powering it down.

Your motor oil experience jibes with mine. I also found tenacious lube too sticky unless it's pouring rain.

Lately, I've been going with "WD40 Bike". It is NOT the same as regular WD40 (when you rub it between your fingers, for instance). I don't know the exact formulation, but it's made (they say) specifically for bike chains, and has been working great since Feb of this year, at about half the price of my old go-to bike shop brands.

Addendum: I see now that the name has recently been changed to WD-40 SPECIALIST® BIKE CHAIN LUBE to avoid confusion. Also comes in wet formulation -- this is new or I did not know.

In addition, I see that Canadian Tire also sells "WD-40 Specialist BIKE CLEANER"...



... which is evidently not intended for lubricating chains, in spite of the little icon of three chain links.
Maybe they mean it can be used to clean chains, presumably before applying a proper lube.

This makes perfect sense.
Once a group of 4 is charged ...

... it's "NO CURRENT FOR YOU!"

But - is there some feature for dealing with a failure in one of the cells in a group of four?

My manual says

Quote. . . as close to 12 hours as possible (but not longer than 12 hours).

For those 12-hour charging sessions, does it have to be continuous?
Say I don't have a timer, could I plug it in and charge for 6 hours, unplug it, go to bed, and finish it the next day with 6 more hours of charging?

If that's the cause, drying can fix it. I believe Radpower says not to leave displays in the sun, but heat from the sun can drive moisture out.

Huh. It's worth a try.
It could also explain the intermittent behaviour, if the ambient humidity is changing day-to-day.
I must have a bunch of silica gel packets around the house. I can microwave the packets to dry them out, and then seal them in a bag with the display unit.
(re: Microwaving silica gel - I used to do that to loose silica gel beads for lightly-pressurized satellite uplink waveguide air dryers.)

I went for a ride up a hill nearby (mostly to partially drain the battery for balancing) and I logged it with the Geo Tracker app (by Ilya Bogdanovich) for Android. I started and stopped the record in my driveway.

I find the altitude data rather confusing though.

Altitude difference	120 m
Max altitude	103 m
Min altitude	-16 m (there was one stretch lower than my driveway)
Vertical ascent	160 m
Vertical distance	309 m
Vertical speed	0.15 m/s

I would've thought that "altitude difference" would be from "altitude min" to "altitude max", or 16+103=119
I have no idea where the numbers come from for the last three.

[later] Ah. I can make a screenshot and attach it.
The biggest climb is going along the straight "pot handle" section from the lower left corner of the lake up the turn-off to "Beech Hill Park".
The side-trip through "Ogden Mill" was on the way back.
