As I said MIPs is not part of any official certification process for cycling helmets it is a commercial IP and as cycling becomes more dangerous, mountain biking or more dangerous again downhill cycling helmets get superior strength and padding due to the greater risk. You can enhance your...

MIPs isn't anything to do with certification, its a commercial IP without any true independent testing because I believe the testing was commissioned by the company itself and has nothing to do with normal certification where MIPs isn't recognised. That's not to say it won't enhance safety in...

My wheel has arrived, very minimal OEM packaging. Includes a bag of nuts/bolts etc but no paperwork at all included with the wheel apart from receipt on the outside of the box. Definitely looks fairly small, not much surface area to dissipate heat and can't be a particularly large planetary gear...

I'm not sure yet, I've not had it delivered yet so will decide when I have it in my mitts. It should be delivered any moment now. Between 12pm and 2pm. I bought this kit from Amazon warehouse a while back for £88 and I'm thinking using bits of that. Even the controller at 22A but I'm thinking...

Is this one of the cheap sports direct/Evans/House of Fraser wheels originally from a Pinnacle Mercury. It just fits the description even has a 13 winding. Best to run from a 36V perspective regarding legality and reduced cog/gear wear rate but from a performance viewpoint 48V would be better...

Geared motor hubs maybe last 8,000 to 20,000 miles and this seems to be the same lifespan of gear hubs like Shimano Nexus. The thing is with a geared motor hub is normally you just replace the 3 nylon gears. On a Carrera like that you have; 1.Battery 2. Controller 3. Motor hub 4...

I'm keeping to mechanical disc brakes just so I can use standard cut off brake levers.

I'm not 100% sure of the frame yet as when I try to fit the hub there could be issues with dropout spacing and the dropout design. I may go with a frame with the beefiest looking dropout that will best fit a torque arm. However I have the Saracen frame and I think a Carrera Subway frame and...

I think the 13 at the end indicates windings which the more you have means more torque less speed I think and will mean the current draw is less so perhaps better suited for the fairly low capacity battery of the Pinnacle Mercury. I can't see the other side is it a freewheel thread or a freehub...

I ordered one myself and also shipped so we will see what happens. Best of luck to the both of us. Yes they may have had a certain number of spare wheels for warranty claims but then found out the hub motors are more reliable than they expected and just weren't using those spare wheels. There...

Yes it's a bit of a gamble but we shall see. Not for one second did I think it was 20A discharge. I knew I was getting 20 2.6Ah cells to get the 5.2Ah capacity battery pack and the pack has a maximum discharge of 10.4A based on the maximum discharge of 5.2A per cell. Gives me a maximum wattage...

I don't consider it compromising the existing charger myself and not keen on inline DC sockets and as I already have XT60 male and female connectors and shrink wrap and this would now be the main use of this charger it seems logical to configure it as default for this use so the adapter takes it...

That top amazon kit wouldn't be suitable for the Bafang based wheel. You need to pair the correct type of controller, that sports direct wheel will be 250W/350W and will need a suitable controller with the correct connector for the wheel and there will be other important parts of the spec to...

As far as I can tell these battery packs typically come with an XT60 connector on their cable so purely plus and minus voltage. Any reason if you have a standard 42V 2A charger not to just cut the cable leading to the current connector and fit on a matching XT60 male and female so the charger...

Thats very useful info thanks. So if charging directly with a charger do you simply make a little conversion cable to go to the correct connector plus to plus, negative to negative or is there any significant components on the main PCB of the device that enables this function. Maybe diodes or...

It's a 624Wh battery but 20A at 48V would be 960W so you'd be getting less than 40 minutes of assistance time if it was taking 20A all the time or about 12 miles maybe of range. People are getting around 40-60Km range or about 25 to 40 miles with such batteries with direct drive motors, less...

I've noticed some people have used these lower capacity battery packs for ebikes but curious how charging works on them when there is only discharge connections and no separate charging cable as far as I can tell. Does this mean they automatically have some sort of charging protection on these...

I do agree that the ebike laws could do with fine tuning to be more realistic but no limit on power wouldn't seem right either. We don't want to see Hummer style tricycles with 10,000W of power that only assist to 15.5mph. 1000W or maybe 2000W peak power (so easy to test) would be sufficient...

The right to repair needs to be combined with reasonable spares costs. Also would Bosch be forced to stop producing highly proprietary products. Maybe ebikes where you could replace the battery pack with cheaper but fully certified and safe third party battery packs? Their whole business model...

When you say 15.4km do you actually mean 15.4 miles per hour. It's just assistance should go up to 25km/h which is about 15.5mph.
