    Noise of Hub Motors

    We have been recieving a range of comments about noise from hub motors. Our experience is the hardest wearing hub motors with laser cut hard nylon composite cogs ARE more noisy than the 8Fun (Bafung) motors from China which employ softer cast plastic cogs. When you open up an 8Fun on the test...

    The Gadget Show Live 2011

    Well, we are exhausted after a crazy show. Some direct sales - yes, people came and put down in some cases more than £3,000 without being able to try the bikes. The season has clearly well and truely started. Stars of the show for us were the Helkama Trike which generated loads of interests, the...

    SURVEY - Research Request

    I am trying to compile a set of Wh/mile consumption numbers. Not to play one manufacturer off against another; I am quite willing not to have brands or marques attached to the data. To produce a distribution, I am asking you to post the following data: Voltage of your battery (V) Ah of...

    Cost of recharging a battery?

    I was asked the cost of recharging a 360Wh battery. Can I assume a charger is fairly efficient. Like, would it cost me 400Wh on my domestic electricity tariff to charge the battery? Thx Bruce

    iPhone and Wireless Networked Bike

    I was asked in another thread why an iPhone on an electric bike..... Our bikes have a IP address and WiFi board on the conroller. Thus it is a simple matter to interface an iPad or an iPhone using an App to the bike. Equally, using a USB to CANbus connector, we can interface a laptop to the...

    Battery Design and Chemistry

    I wonder if anyone knows of a good and accurate review of the currently available and used, not reseach dreams, electric bike Li battery chemistries and technologies. For example, there appears to be lot of erroneous material in electric bike marketing documentation about the batteries used...

    Range and Wh....

    Reposted from another thread where it got lost and I was justly accused of hijack for which sorry..... We have been working with Barcelona Tech and using our iPhone wireless network to monitor a large number of riders and routes around Barcelona City and out into the hills. Thus we have an...

    Electric Bikes - Brands and Prcing

    I been away a few days at the London Bike Show and a couple of things have struck me. One from a thread here which noted: "The two Bearprint Company owners Phil and Steve were very approachable and helpful both via email and by phone during my purchase of the Ebike. They confirmed that the...

    London Bike Show (Outdoor Show and Boat Show)

    We have just returned from an exhausting and very very busy four days at Excel in Docklands. We only agreed to go on last Monday and, as I think many of you know, we are a start up and hence had nothing really ready in terms of stand dressing!!! Off to the local colour copy shop for fliers...

    London Bike Show - iPad interface

    A subset of the Outdoor Show - next to London Boat Show. At very short notice given the relatively low stand prices, we have decided to exhibit. I notice Spencer Ivy, Batribike, EBCO and Freego will also be there. For us it will be a bit of a taste it and see for future exhibitions. We are...

    New Battery 'Fair' Prices

    Is the market efficient in Wh? Or, in other words, do you pay the same per Wh for a spare battery irrespective of manufacture. My gut feel is the 24V 10Ah Panasomic costs £400 (inc VAT) to replace for e.g. a Kalfkoff, and that the Wisper 36V 10Ah costs about £400 (inc VAT). Yet the former...

    Crank Bike with Throttle?

    I was wondering if there are any Crank Bikes (Panasonic or whatever) with a throttle on the handlebars, and if so how well they work. For people who want the option not to pedal - possibly with a medical condition that sometimes is a problem after 20 mins light pedalling and sometimes is not...

    36V Hub vs 26V Crank

    I tried in an earlier thread and confused everyone, sorry. Can I start again: In the real world, would one expect a 36V 17AH Hub motor bike to go further than a 26V 18Ah crank? How far in each case - modest Doreset hill, 14stone bloke? After say 20 miles on each, would the bloke...

    26V 18Ah Kalkhoff vs 36A 16Ah Wisper

    Been lookikng at boats in the summer but just came back to the forum and noticed the new Kalkhoff battery... Just a piece of curiosity? One for Flecc certainly :) 26V x 18Ah gives a Wh of 468 36V x 16Ah gives a Wh of 576 That means the Wisper goes further. Am I right? But is it...

    Gadget Show, Top Gear, others

    Help - Police impound bike

    Hi guys, Back after a break. Just for the record, I am no longer working for Bearprint Bikes. On a totally different topic, I have just heard that a contact of mine was stopped by the police last because it was illegal. It was apparently going well over 15mph and the power was still on -...

    Survey of Expert Opinions

    Four questions, if you have time? Thank you: 1. I am wondering how many electric bikes are sold in the UK each year? 2. Like, what is the prediction for 2010? 3. And how does that breakdown between <£1000 and £1000+ purchases. 4. And do people buy from the web or from bike shops...
