    Haibike Xduro Trekking SL 2013 Review

    Seems we agree. I've posted a few times about the Bosch system on the Rose being no mountain goat, although the extra 50 per cent assistance on the AVE makes a difference, among other things. You've posted a few times about your 500w ebike being faster and more powerful than a Bosch - I don't...

    Haibike rc29 first ride.

    Don't take too much notice of the range indicator - it goes up and down all the time. You arrived at work with three bars on the battery which is a good indication you have more than half left. This is supported by the general notion that an 11ah Bosch battery will do about 40 miles. So I...

    My new bike

    A couple of psi here or there makes little difference, but on my bikes I can certainly feel the impact of 10psi more or less. Suppose one ought to check one's tyres every week, or at least every fortnight.

    My new bike

    Well, the bloke who pumped up the tyres in the shop could have told me they would go down after a while. Seems I've been riding recently with about 35psi front and rear. Put just under 60psi in the front, which felt plenty hard enough. A few more psi in the rear - with a nod to Sheldon. Did...

    Battery Charging - Opinions Please

    Or put another way, the gadget in your house most likely to burn it down is your ebike battery/charger. I'm not too worried about that happening, but the precaution I do take is only charge when I can keep an eye on the battery. Easy with the Bosch ones because they charge in a couple of...

    Battery manufacture date and effect on it's lifespan.

    Range is heavily dependent on hills, headwinds and how much grunt you dial up from the throttle/controller. However, a good rule of thumb is between three and four miles per ah. You have a 15ah battery which gives a range of between 45 and 60 miles. Which I happen to know is correct because I...

    Abuse when wearing helmet cam

    That is a genuine shame, and not easy to deal with. One way to look at it is to worry about them as much as they worry about you - which ain't an awful lot.

    Scorp, Don't worry about d8, he just doesn't like Bosch bikes.

    Abuse when wearing helmet cam

    Of course, you shouldn't have to alter your chosen mount because of nasty people. But realistically, as a lone cyclist - male or female - you are an easy target. I get very little abuse, but when I do the only sensible answer is to ignore it. Today I went out with a group of about 15 riders...

    Abuse when wearing helmet cam

    You could mount it on the handlebars and people wouldn't notice or would think it's a light,

    Back on the road

    I had a nasty, aggressive taxi driver when I left hospital after a hip replacement. His driving was unsafe, but I was not about to let anything interfere with my precious new hip after going through so much bother to have it done. I don't know if he fully understood my remark about me giving...

    Raleigh Velo Cite

    I tried a 2013 Velo and was disappointed - the way the power cut in and out was very clunky. That might be one of the improvements for 2014. If you've tried the secondhand one and like it, fine - I won't be riding it, you will. The bigger battery is an attraction, depending on your proposed...

    My new bike

    Thanks for the links. Seems 70psi is plenty, although I take Sheldon's point about there being plenty of headroom in the max rating. The tyres on the Rose are 2" '29er' Marathon Supremes, which are a bit balloon like, but I reckon are harder compound than the Big Apples. Conclusion is the...

    haibike bosch motor?

    Dunno about plastic gears, but you can certainly buy replacement displays of both types. Not that mine will get the chance to fill with water unless I crash into a canal.

    My new bike

    Thanks. Just back from another 25 miles. No doubt there is some rolling resistance from the tyres. Does 70psi sound about right?

    haibike bosch motor?

    I have two Bosch bikes and can confirm the system is more or less bomb proof. It's not the most exciting ride, but I like the close rendition of ordinary cycling. The bike bits on a Haibike ought to be decent quality and, just as important, serviceable and replaceable. I wouldn't worry too...

    My new bike

    Done a good few miles now and still pleased with the bike. The extra poke from the Bosch/derailleur is noticeable, improved still further by the small wheels - sharp acceleration up to my chosen (low) cruising speed. Handling of the bike is much nippier than the Rose. I pulled a wheelie...

    Be Careful Out there...

    That a bicycle remains upright at all is something of a triumph over gravity, so it takes nothing much to unbalance one.

    Caught someone driving badly via my cam, am I allowed to put it on youtube with the car reg on?

    Don't expect a lot from the cops, they don't like being presented with evidence because they see it as an ignorant member of the public telling them how to do their job. If you do contact them, use a bit of reverse psychology: "This video is probably a load of rubbish and not worth...

    Punctures

    I can't go back that far but recall patching car inner tubes as a Saturday boy at a garage in the 1970s. We had a roller to flatten the patch, and I think what was called a vulcanising machine. That was a press which applied a tiny bit of heat to the patched area, presumably to make the...
