    Orbea Gain e road bike

    the main reason for me getting the obera is that if get it in black, wrap some innertubing round it, it will hide in a rack of other bikes as a non-e bike..(it’s also insured) I’m getting the basic non-hydraulic dropbar model due to wanting crosstop breaks (i know they are **** but stopped at...

    London Scott E-Silence Speed 20

    not an issue. it paid for it’s self in transport fees, and the household insurance paid out nearly everything .. just a bit boring.

    Orbea Gain e road bike

    tested one last week, up a short 55m primrose hill (london) and it was fine (i’m a middle aged asthmatic). Not as fast as previous bikes i’ve used i.e. e-silence. But not too far off. I’m ordering one based on that and hopefully it will be ok (i live at the top of crystal palace hill, and need...

    London Scott E-Silence Speed 20

    Sn: gj678644 1 year old (so thankfully paid for it’s self in travel costs) Has a small nick on the top tube where someone tried to hack saw through the frame instead of the lock previously. £80 lock sawn through with a circular saw at 7pm on a Friday night on a shoreditch high street! Left...

    Brose 'BMZ Sportives Display' Tuning help

    The Specialized levo version of the Brose has these 'tuning' tutorials (to change the size of the wheel in software): ....but i can't find any info on how to do it with the BMZ version of the bike - i don't think it has bluetooth. (i have a scott e-silence - 30% off in January sales!) -...

    Pedal resistance

    Wow lots of geekery. Although most interesting and impressive, I'm hoping to find out which mid-drives have the least pedal resistance pls?

    Pedal resistance

    Thanks good to know.. Also its the Shimano Steps motor that a reseller was claiming had less crank resistance than any other current mid-drive.. Has anyone compared this to the Brose in this respect? ...also little wierd that on the shimano site the ,more powerful Shimano Steps E8000 is listed...

    Pedal resistance

    Hello Pedelec world, Do people know what sort of extra resistance e-bike motors generate when over the top-speed cut off please? I know from experience that the extra weight slows one down. But it's difficult to tell when riding if its the weight or the pedal resistance. I've read that the...

    Thoughts on the UrbanX eBike kit and other complete-wheel kits

    Its the "thus doubling the effective weight," that is misleading not your post d8veh. From how i have grasped the explanation of the physics behind this, the extra rotational weight would be on acceleration not deceleration. However as you have clearly pointed out any extra weight on front...

    Thoughts on the UrbanX eBike kit and other complete-wheel kits

    Rotating weight make a small amount of difference and only when accelerating. Admittedly the weight difference here is huge, but a Copenhagen Wheel, compared to a traditional rear hub is not that much difference in weight (and comparable to on-line tests of bicycles with heavy vs light rims). I...

    Commute Road Bike Build front/rear hub or mid-drive?

    Don't you know its rude to ask a middle aged man his exact weight. ;-) I'm about 11 stone. But how to chosse between rear hub or midDrive you recommend (apart from the current legal issues)? O.T. Yep... i guess the current laws are inadequate and a new class of vehicle will eventual be...

    Commute Road Bike Build front/rear hub or mid-drive?

    Good info! - Good to know that its easy to fix a flat on a rear hub, as long as i have a pocket alu. cycle spanner & I will check for horizontal drop-outs So a belt drive is a no-no for me as it would require a new frame (but defo. something to look out for...

    Commute Road Bike Build front/rear hub or mid-drive?

    I've been riding a Sparta r10i for the last two weeks dong 18miles a day including living at the top of crystal palace hill and its been amazing. The list of features is outstanding, it's super robust, extremely comfortable and a wonderful piece of engineering. But... it's not what i'm used too...
