    Belts v Chains

    Thanks to Harry & Flecc for links - note to self, try hitting search before reply now and again! I can understand the depth of a toothed belt giving rise to the stretch & compression soaking up energy and along with the friction creating heat. This kinda suggests that a belt with as thin...

    Belts v Chains

    Dare I ask why? My car cambelt is good for 4 years / 60,000 miles and gets wet & dusty My simple logic finds a belt drive combined with my hub gears a possible low maintenance option. What am I missing? All the best Bob_about

    Setting a Standard?

    One last try, and then 1`m out too! My interest in this thread went like this- Current approaches by manufacturers and suppliers give confusing and inconsistent advice regarding range (I posted an example where the same Wisper 905se 14Ah Sport was quoted with four different ranges on...

    Setting a Standard?

    The current situation is ridiculous (IMHO) Come back to this thread this evening and it continues to be interesting. Excellent explanations from Flecc on the complexities of the Panasonic system, it is clearly way more sophisticated than I had realised, even after riding over 40 miles on an...

    Throttle free control system

    Dial Assist Control Hi Phil, I had the throttle on my Ezee Sprint removed and replaced with a dial assist control at the time I purchased it. It took Andrew at OnBike 10 miunutes to swop it over and it connected into the existing wiring loom as a straight swop. Normally the bike...

    Setting a Standard?

    OK Flecc – so you think my analogy is irrelevant – I`ll not take that personally! Thanks for directing me to your earlier posts - I had read them previously and I understand what you are writing. The car anaology works for me and I thought I`d share. The point I was trying to make was that a...

    Setting a Standard?

    Not all consumers visit this forum! Whilst we all agree there are many variable and any standard measurements would not reflect what would be achieved on every ride, the establishment of an agreed set of baseline figures has got to be good for the consumer who is currently faced with a...

    Lifecycle City Sport

    Hi David Can I say I think this would be an excellent idea and really help current owners and potential new customers to understand likely ranges better and be able to compare different makes and models. I understand the need for manufactorers to promote their products in the best light...

    Lifecycle City Sport

    60 mile range ?????? Hi again, Just to echo what Eddio says about taking published ranges with a pinch of salt - make it a 2kg bag! With a 14 Ah battery running at 80% efficeinecy (you never get 100% out of a battery and should not try) you would need to average a demand level of 7.2...

    Lifecycle City Sport

    Try before you buy Hi Hurricane I`m not sure if you have ridden either bike on your shortlist, so forgive me if I am being impertinent, but my recent experience in choosing a new bike surprised me. Like you I had almost decided to buy a Wisper City S based on internet research, but...

    Cheap Charger - what could possibly go wrong?

    Like it says in the title Saw this on evilbay. I seem to recall a post stating that modern batteries with a decent BMS would adjust themselves to the charger used (or did I imagine that?). So is it worth a try, or would I be stupid risking my expensive batteries with a cheap charger...

    Insurance

    Cycleguard is Chaper via Evans Cycles website Whilst I appreciate that many may consider me mad to have spent £170 insuring my bike and public liability for a year, for the few who may consider such a move it may be worth going via Evans Cycles website. The insurance they are offering...

    Data gathered, evaluated and decision made!

    Charging Cycles My thinking was that I should have enough power in two batteries to travel there and back (40 miles) and have used about 50-60% of the mathematical capacity. So I guess the question to ponder is whats best for the batteries: 200 charging cycles a year of approx 50% 400...

    Data gathered, evaluated and decision made!

    Thanks for the good luck Eddieo - quite excited about getting underway. Ref 16Ah 36V - that would hold 576 Watt Hours, assuming that on cold days around 80% of that would be available I could expect to have 460.8 to play with if I completely discharge the battery. Based on my tests I`d...

    Data gathered, evaluated and decision made!

    Hi all I joined this forum with two purposes in mind – first to ask questions and learn from others experience; secondly to share some of my experiences where I feel they may be useful to others. This post falls into the later category for anyone interested in how one person with quite...

    Anyone want to share a set of panniers?

    I have other Ortleib kit to support my Kayaking obsession so am familiar with their quality and am happy to pay their prices. Waterproof with Ortleib tend to mean waterproof (unless your forget to clip it up and leave your sandwiches in the back of the boat while letting it get full of water...

    E Bike Profit Margins and discounting etiquette

    To date, my most expensive kit purchases have been to support my Kayaking kit addiction, new boats, drysuits, paddles, helmets, buoyancy aids etc etc – very few purchases have been below £100 and I have a good relationship with my two local shops and a number of on line retailers. With these...
