Re: E bike conversion

Can I recommend a crank drive motor, such as this Bafang BBSO2 which I've fitted to my 27.5 hardtail. Easy to fit, low centre of gravity and the bike pedals fine with it turned off. I put a big 15ah battery on, which lasts 4-5 hours off road, but a 9ah would be ok and much lighter. I used to ride hu...

Re: Brompton Electric Conversion Advice please

I've converted a couple of Bromptons to electric for friends. Both using Nano motor kits. The radial spoking works fine, the rims look very strong. The battery on the newer kit was a 4aH Bosch, like that from a large Sds drill. It fits in an adapter in the front bag. Carrying the the folded bike in ...

Re: Schwalbe Marathon Vs Marathon Plus tyres.

I fitted Marathon Plus 29er tyres to my wife's ebike...they've been excellent and much better than std Marathons. After getting a flat from blackthorn following the hedge cutter, I put about 50ml 'Stans' fluid in the schraeder tubes; to date, no punctures after daily use on poor Cornish lanes. I've ...

Re: Dartmoor

Hi Phil, I've ridden many of the bridleways on Dartmoor; it's been very good this year due to the lack of rain. Look on the Dartmoor National Park website for info. on campsites, wild camping and mtb routes etc. Along with the OS 1:25000, there is also a very useful on/off road cycle map (Hartley?) ...

Re: Prescription cycling sunglasses with lenses

I've used Puma ones from Specsavers for the last 4 years; clear, orange and dark lenses. Really good and about £90.

Re: Compact double road

Hi Si, If you are really only using the little chainring on your compact double, why not give 1 x 10 a try on the gravel bike. I have done just done it on my trail mtb. Sunrace MX5 11-40 cassette, 32 tooth narrow wide chainring, 104 bcd, bolted to inside of Deore chainset, has good chainline. The na...

Re: Find a MTB triple chainset in SILVER, 165mm cranks

I recommend trying a 'range extender' rear cog, 40 tooth for your cassette. I've done a few of these for people, albeit on 10 speeds. There's no reason it shouldn't work with ( speed and your LX mech. It's a very neat solution, and you don't change your front set up.

Re: advice needed - upgrading to my first carbon road bike

Back to HMB's original post about upgrading to a carbon road bike; I did just that a few years ago, from an alloy Giant Defy to a Planet X Pro Carbon with 105 groupset. I love it. It is lighter, but the real gain is more comfort, which is often ignored is these carbon discussions. I also ride a (sec...

Re: Suspension fork suitable for hub motor?

Hi Rotavator the fork was a steel Surly Instigator I think, with disc mounts; unfortunately it sold yesterday on another mtb forum. I have another one, quite similar on an mtb/hybrid hub gear bike currently for sale on this forum, if no one goes for the bike soon I will split it and give you first d...

Re: Suspension fork suitable for hub motor?

Hi Rotavator, I would advise against using alloy suspension forks with a front hub motor. I tried it a few years back on some rockshox and the anti-rotation washers tore the drop outs apart resulting in an over the bars crash, at low speed fortunately. I have fitted quite a few front hub motors to m...
