I try not to think of it any more. As soon as I past the £700 mark I lost interest in the cost.

Main thing is you enjoy it.

Seems the belt is being tightened. Just been stung for an extra £16 on a £20 item from HK, that's £4 VAT plus a ' clearence fee' from a company in London that I've never heard of. If this continues I'll certainly pull back my spending which completely goes against what's needed in these times of financial worry...
Another example - if you overstay your ticket at the pay and display of a certain Council you're invited to pay by card. In very small letters it says "Debit Card only".

If you ignore the warning and pay the £20 by Credit card, the system will apparently accept your money - but fail to collect from your card! A month later, you'll get a demand for £40 ... but this time they'll accept the Credit card payment!

Neat trick, huh? I know someone else this has happened to.

So what do you recommend d8veh
The Cycle Analyst is a bike computer that also shows and records battery information so that you can accurately predict your range and see how you and your battery are performing. You get them from Ebikes.ca. You can also use it to limit your speed or protect your battery from over-current or under voltage. About £105 direct from them inc. postage.

Very nice but a bit pricey for my use. I only need the bike for leisure and don't intend doing more than 30-35 miles in one trip.

What about this one as an alternative.

To mount it on the handlebars where you can see it, you either have to have thick wire running all over the place, which looks very untidy, or you have to unsolder the shunt and wire it externally. I prefer this one because it's easier to remove the shunt. I normally pay about £16 direct from China, but can't see any listings at the moment.

A few of us use the turnigy watt meter for that.
I personally use one. Good little thing for the price. But as Dave has said above the cycle analyst is much better with more features and allows you to change settings on the fly.

Nothing wrong with the turnigy ones there but limited. But at a 5th the price you can hardly complain. I also run a few low voltage alarms as there light but rarely use up the full amp hrs. The ping will last for ages anyway.

Did you do the remote shunt mod? If not, where did you mount it?

Mine sits up front :p



It is easy for my setup as my controller and battery are in the front bag.



I have never found the screen that easy to read on the move though. I used it quite a bit when I first built the bike to check current and the trip capacity of the battery I was using, but having worked all that out I now rarely use it.

I did do this when I had the 36v battery mounted on the rack. I ran it up to the handle bars and tie wrapped it on the stem.

As soon as it hit autumn/winter and I got rid of the rack and went Lipo I ditched it and just left it in the bag with the batteries. After using a 10ah 44v battery for a couple of weeks I was using around 8ah as I changed offices. This meant an extra 2 miles each way. Hence the extra amphr each way plus winter so it was colder i didn't want to get caught with my pants down on capacity... So I brought that winforce lipo battery 5200mah to add to the 10ah battery.
After a few commutes I now know I can safely do the journey without even getting close to full draining the battery.

Now I've changed the bearings and increased tire pressure again I'm getting close to 18watt per mile. Giving in theory a range of 36miles. Even at 30miles I have more than enough capacity to keep me going.



In any case the cycle analyst is worth the money. Anyone that seems to have purchased one has not look back. They also allow up to 100v as well as a higher amp limit.

The turnigy only goes up to 60-63v without burning out. So for modders this only records so far. Anything custom made without BMS's at least needs something to clock the figures on.

Finally finished the Claud Butler for my better half. Took both bikes out for a run today.

We did get a fair bit of dirt spraying up from front wheel. Down tube mudguard is not much good. Any suggestions for decent front mudguard would be appreciated. Can't go into a pub on bike run all splashed in muck.

I reckon it is 25% Both batteries cost £802 so a quarter is £200. VAT is 20% and import tax I am guessing at 5%

Just wasn't expecting such a hit, That makes each battery costing just over £500 That is more than the Synergie Cruiser for the whole bike!
Old post, but thought I'd comment on this for anyone reading it.

You have to understand the way import VAT is calculated as to why it can seem so high and much higher than 20% VAT sales tax on domestic goods.

Customs make couriers follow a standard practice across the EU (EU law) which means they calculate Duty (about 3.5-6%) on the goods value first, and goods value means cost of goods + shipping + VAT on shipping. Then import VAT at 20% is calculated on top of that final price.

But here's the sting. EU law makes couriers use a set scale of minimum shipping cost where the shipping fee is not stated (with proof) on the paperwork. Often this shipping estimate is much higher than what you actually paid.

Yes it's a racket. The end result is you often end up paying 30-35% import taxes on your goods.

Also there's the £15 clearance fee/deferment fee routinely extorted by couriers just for paying the VAT/Duty for you through their account with HMRC. This is also a racket and basically a way to exploit customers and make incredible profits from doing very little. I have checked with HMRC, and customers (and businesses) who are importing goods DO NOT have to pay on deferment accounts with couriers, you can ask the courier to pay the taxes DIRECTLY to HMRC and they cannot refuse you. Often if you argue over the £15 fee and say you didn't request that service and preferred to pay it directly, the couriers will just drop it and not pursue the fee. You don't have a written contract/agreement with them after all to pay for any service and it's not worth them pursuing you for such a small amount. So stand your ground.
