    Haibike Hard Seven-Has Anybody Fitted Double Chainring ?

    Yes I have done a conversion on a 2016 Hardseven, easy enough to do if you need the gearing. I'm living in the Alps part time and certainly find the extra low gears mean I can give more of my input when climbing and particularly when off road on tight technical climbs it is easier to pick your...

    Haibike cassette replacement

    It depends on the quality of the parts used, I had some parts so didn't need to buy everything. You need a direct mount front derailleur a left hand gear changer (these 2 parts can be found second hand on ebay) a cable and 2 9 or 10 speed chainrings.

    Haibike cassette replacement

    Or convert it to 20 speed if you need the low gears. I have a 2016 which I have fitted with a 34/44 front sprocket combo and have done a couple of thousand km with no problems in the Alps. I rarely use top gear with this setup so wear on the 11t sprocket is not an issue.

    8-FUN BBS01 Crank kit on Boardman MTB PRO 29er

    If you use one of these with a direct mount front mech you should be able to get the reach that you want. http://problemsolversbike.com/products/direct_mount_front_derailleur_adapter/

    Air compressor

    Don't think that will do what you want as it doesn't seem to have a tank. The usual method of use for a small compressor is to let tank pressure build to just below cut off then start using it, as pressure drops pause and repeat.

    haibike tyre

    I was given a pair of DHFs over the summer, the grip is unbelievable off road but they are hard work up the hills (I am constantly looking for more range so low rolling resistance is good. I have in the past used High roller and Ardent as winter tyres on an unpowered bike and may try this combo...

    Haibike sDuro HardSeven 2016, Front Chainring increase.

    As far as I know (I have a 2x10 conversion on mine) 1. Any 104 pcd chainring will fit most brands stop at 48 2. On mine I did not need to change the chain using a 44 and I believe a 48 would still go as I also have a 40t rear gear and that is fine. Not that I would use the outer and bottom gear...

    Converting 27.5 to 26

    Cringe. You got me there. Mine's a Yamaha, I usually don't post about anything other than Yamaha as I don't have experience of anything else .

    Converting 27.5 to 26

    So in this case just about then, you've just given everyone with a Nyon a free dongle;). Can you do this with an Intuvia as fitted to a 2016 XDURO?

    Converting 27.5 to 26

    Please don't post on things you don't know for definite, there is far too much misinformation on this forum. I appreciate you are trying to be helpful but you clearly do not have any knowledge of this particular bike or its drive system.

    Converting 27.5 to 26

    I'd like to see the shop that can lace a Bosch crank drive motor into a wheel! No you can't change the wheel size in the display, not sure if a dealer can do this with a software update.

    Gears and Tyres

    You can usually hear where the puncture is a ferry putting some air into the tube, if not hold the tube close to your top lip and rotate it. I rarely repair punctures at the roadside, just stick a new tube in and blow up with a CO2 inflator, no effort required. I don't have a hub motor which...

    Gears and Tyres

    I haven't missed the point. The Schwalbe tyres fitted as original equipment are usually rubbish. If you look on the Schwalbe website site you can see all of the variants starting from cheap heavy hard compounds to light fast Kevlar bead. The range of Racing Ralphs for instance is quite large...

    Can I derestrict my 2016 Haibike Sduro Nduro for private Land use?

    It's would half the speed and distance readings.

    Can I derestrict my 2016 Haibike Sduro Nduro for private Land use?

    Not all dongles keep the speedo working correctly, most of them read ok up to a certain speed (below cutout) then they cancel every other or 2 out of 3 pulses so the speedo reads half or a third of the correct speed.

    Gears and Tyres

    They aren't high end tyres, they are cheap OEM hard compound wire bead tyres with the same name name and tread pattern as the expensive soft / multi compound tyres with Kevlar beads, puncture resistance etc. Bear that in mind when buying, if you want decent tyres then you will need to replace...

    Universal Bike Carrier for ebikes

    If it can take a towbar then many towbar mounted racks will fit. A lot of them will take an ebike without problems.

    President Trump

    Looks to me like after this and Brexit both going very much against the establishment that western politics needs to take a long hard look at itself and get more in touch with the general public. You could also add the illegal immigrant crisis to this.

    Cycle Commute below zero?

    You can leave them on no problem. A couple of issues I have had commuting in winter : sometimes particularly with fresh snow on top of ice the layer that you have grip on can slide on the ice underneath, spiked tyres do not help in these conditions. : if snow becomes rutted by feet, cyvle...
