I was interested in where the energy to power a bike goes and the various bike design parameters, not really specific to just electric bikes e.g. 1) weight - at first I was thinking this only really applied to hills, but I'm realising that there are very few completely flat roads and even on a...

So the latest fitness craze seems to be "Zone 2 Training" which is training at 60-70% of your heart rate for relatively long periods (40 -60 mins) at least 3 times a week. https://www.gq.com/story/why-easy-zone-2-workouts-became-the-biggest-thing-in-fitness Among other benefits it is said to...

I went for a ride this morning and my battery voltage (measured with multimeter) fell from 54.6 to 48.1 and I travelled 31 miles. If I travelled the same route at the same level of assist, what mileage range would I have left before the battery was "empty" ?

So my 48v 15amp controller is in a little bag behind the saddle. I have already drilled some holes in the bag for ventilation purposes because I guessed it might get very hot. Anyway, today in my jaunts round the tiny back roads in the North York Moors, after lots of 10% , 15%, 20% and even 25%...

So I'm on the edge of the North York Moors, and I had a little ride into the moors this morning and was just struck how much fun it is on an e-bike. Cycling up one of the long hills , I caught up with a Lycra clad road cyclist and it just looked like really hard work, whereas I could do this in...

I occasionally see bargains for sale and I wonder if they would suit othere pedelecers I was going to post them here, feel free to join in

Saw this on a Facebook marketplace advert, looked tidy for £90 , possibly just needs replacement battery ? Unfortunately rim brakes https://www.facebook.com/marketplace/item/1502809347156732/?ref=facebook_story_share

This popped up in my feed, seemed alright for the money although manual disc brakes and not UK legal https://www.gunai-ebikes.com/products/gn29 Someone did a review here

On my conversions I have a + and - button to adjust the pas levels. Is there any invention where the assist power is on a "slider" or twist slider so , for example , I can just twist or slide one way for max assist, the other for min assist and in between, the more I slide/ twist the more power...

So I understand that controllers can have speed based PAS levels or power based PAS levels. For the speed based PAS levels are these controllers just applying maximum power at PAS level 1 until you hit the PAS level 1 max assist speed ? I wondered if it was done on Voltage - so PAS level one...

My niece (who is medical student) has asked to "borrow" my Claud Butler step through which I converted (which sounds like a good way of getting around campus !) I will have to give her strict instructions on battery care !! So I could do with a "road bike" as well as my Boardman 29er BBS02B...

Hi all, For my next project I was going to do another rear hub conversion of a Whyte Calendonian hybrid. I have already a mid drive 48v BBS02B conversion of my Boardman 29er. I wanted to be able to swap the Hailong 48v 20ah battery (Samsung cells) between these two e-bikes depending on which...

Hi all So I wanted a "tootling about" pedelec to go with my BBS02B boardman conversion and I thought I would try doing this one myself (bit of a novice bike mechanic!). Not going to use it for commuting or in heavy traffic, just day trips on pretty deserted single track roads and maybe cycling...

I was curious about the 705 assistance levels. How do they work? is it a percentage of full power or a maximum speed within a level or both ? (Jan had hers on level 5 yesterday and it was flying along, I think she prefers it in level 3 and then adding throttle where needed.)

So, becoming a bit of a pedelec missionary after converting my Boardman 29er mtb, my wife getting a second hand Wisper 705 and sorting out my sister's 10 year old KTM Macina Cross so she can ride it again (Thanks @soundwave - got the NX branded battery from allbatteries.co.uk) Next project is...

My sister has a 10 year old KTM macina that I thought I would get going again for her. I've changed the inner tubes and sorted the brakes but the battery is knackered. It's one of these https://www.bike-discount.de/en/bosch-powerpack-400-frame-battery-white-classic but they won't ship to the...
