Very impressed so far. The speed is very good, but it's the grunt of the thing up steep hills that really makes an impression. Range still unknown, the one small issues I have is with the battery, the gasket seal is slightly damaged where it wasn't seated correctly. I'll probably just seal it...

I think its horses for courses, and some common sense is required. I wouldnt use a Thunder Horn on a quiet canal towpath as the pedestrian may end up in the water! Similarly the small ping bells are completely unsuitable for busy, noisy city centres, where about a third of pedestrians have...

I've ordered a Thunder Horn from eBay, i'm hoping it will help one particular city centre area of my commute. :D In the morning the said road is a normal road, but after 8:30 bollards rise and close it off until after evening rush hour. Buses and emergency vehicles automatically lower the...

Yep, sounds like diesel. I usually smell a spill before i see it, 14 years motorcycling has hard wired "slow down" to that smell. I would also point out that the new sticky grit, with added molasses is actually very slippery itself when on two wheels. I hate the stuff. Does your Dawes have...

In that case the calculator must be way off, or the figures i'm feeding it are. I know my hub motor on the cyclamatic is meant to be 250w and comfortably does 16mph on the flat on throttle. I can match that with the throttle turned off, for a couple of miles at least, and i can sprint to over...

I've found the routes with a lot of fast downhill where you can comfortably exceed 20mph are faster on an normal bike, but more hilly routes are faster on an eBike. And the difference is in the eBike's favour, by a large margin for me.

Interesting calculator, on my old purely human powered bike it appears i was consistantly outputting 80-100 watts, with peaks of up to 300w for less than a minute, and i consider myself fitter than average. They say top pursuit track riders can hit 2000w from a start, although that tails off...

This could be one of a few things. 1. Check the pedals are on tight, and rotate freely, it could be a pedal bearing. 2. Check any bolts connecting the chainring(s) to the crank are tight (this is the most common one). 3. Taking one crank arm in each hand, check for play agains the...

With a higher end digital turbo trainer, a heart rate monitor and a bike computer with cadence and speed you could get some fairly consistent results. Of course thats very much not "real world" though. And i suspect you might struggle to fit rear hub motor bikes on the trainer which usually...

The Tweel either doesnt work or is the longest product development ever here's a link to a car club talking about it in 2005, with a photo of the same silver Audi...

I saw these quite a long time ago, there was much discussion about it on a motorcycle forum i am a member off. The key problem pointed out there is just as applicable to bicycle use. If you make a curved radius tyre the flex of the "fins" would be restricted, and although that could possibly be...

Alien Vector Trike

Erm, reporting them to who? And what happens next?:confused:

I was in Halfords today (for some bottom bracket bearings) and they had a good range of mirrors, including one just like the eBay link Blackpanther provided. FWIW they didnt have the bearings, but pointed me in the direction of a shop that did. Seems i actually found a knowledgable Halfords...

I've never found them to work for me, and as the oozing slime make patching difficult i dont use them anymore.

Agreed, most cycling forums have an Events & Rides type forum page.

I'd recommend RockShox Dart 2's on an MTB, they'll fit, and perform better as a suspension fork, but you lose the mudguard/rack eyelets. They take either disc or v-brakes. £85 at Evans Cycles, some place selling for £75 online. Dart 2

Ah, must have one of those Blackpanther. Ordered, thanks.

I've heard of it happening in laptop and phone batteries, but really its so rare that i'd not worry about it. Its always been a rechargable battery risk, i remember a set of RC racing nicads exploding on me in the early nineties.

d8veh, thanks. What type of crank interface is it? Square taper?
