My old king meter display allowed speed change, though had no set pass code.

For the controller load demand with all the weight and the small high speed/rpm/ wheel size combo, one is asking to much for the bike on throttle alone. As one has found out the limitations of a slight hill fully or overloaded will put too much burden on the controller/ motor to cope very...

43.9v is 3.37v per cell group so you are verging on lvc, the fast speed will eat the voltage so maybe reduce your speed some. For your bike sounds like you need to charge fully all the time, at the speeds you are doing it is futile allowing the charge to go down and expect the same performance...

Show us a pic of the forks. What material are they made from ? Are they QR or thru axle/maxles ?

Ouch a painful and horrible injury, I broke my ulna a dozen years ago and was in plaster for over 10 weeks. Recovery will be longwinded so wish you well. On another note what happened to Bertie was he /she injured ?

Controller rating with that kit is 18a +/- 1a so one needs a battery ideally with a 20 - 25a continuous rating. One has to be wary of china battery claims of 100ah, they will be false and misleading. Buy cheap one could be buying twice if not 100% sure of the product. For 13s3p the max for...

Typically one can get them ranging for 10a - 17.5ah but more importantly one needs to check the battery discharge continuous current and that it is rated for at least 20a continuous ignore the max temporary rating.

Nearly all silverfish battery have a two wire connection only as they are a simple dumb generic type battery, what one has to look for is how many discharge prongs on the base some may have only two some may have 4 or 5 with only two being used. That said most of these battery come with a new...

The original will have used prismatic pouch cells or Li- polymer, most bikes tend to opt for li-on for a higher degree of safety.

It's not whether the battery can power it because it can. The question should be asked is, can the battery continuous current rating provide more power for the max current draw of the controller. The battery in the link is only 15a continuous rated, ignore the red herring of 45a max...

One can buy the battery a silverfish and a charger quite reasonably from all the usual market places here and in China. One won't find a dual setting generic charger but just needs one that is for 36v battery, the 39v setting is a storage charge setting which is quite a good idea if not using...

As fuel prises rise I think more people are thinking abut their car use esp when £40 only buys about 6 gallons now and it will only go up plus the younger generation are more with it and are trying to lead the new revolution in the way we live and travel.

Trevor there are definitely less vehicles on the road after 6/7pm, I drive part time for some beer /hobby money. The roads are certainly quieter later on but that may change once the nights draw out again in the new year. So far esp during the day I have noticed a lot of traffic is a bit more...

No case has ever come up afaik, two motors is illegal even if one say's the second is for private land use. Again no case has appeared in court though one could have the bike confiscated by plod.

One suspects a wiring issue with the new connector. Explain clunking a bit more.

Depending on where one locks the bike and under what circumstances may dictate the crook who is going to try and steal your bike. A chancer like a nomad is always likely on the prowl and and then targeted bikes esp if a routine is noted, they then can take it at will when they wish. Cycling to...

Oxford sell the D lock pro, the 16mm steel should resist bolt croppers but like most won't stop a disc cutter for more then 60secs, It does though have an in built 120db tamper alarm. Other possible's are; oneguard brute ls8000, the newyork has been mentioned and two abus models. The granite...

One good thing about buying from a reputable ebike producer in the UK, parts are available unlike some vendors.

I have three baseplates for the dolphin 09 battery so yes depending on the battery box type they are available.

Fitting a double isn't too troublesome, the chain line may not work for all the gears but one will certainly get at least 5 or 6 gears high gears from the large chain ring and likely the 5 or 6 low gears with the small chain ring. You might be ok and get all gears just depends on the chain...
