Vectrix scooter revisited

Canary Wharf Motor Expo was on again this week, and I bumped into the people from Vectrix once again. This company makes an electric scooter called the Maxi Scooter which I rode a couple of years ago and was very impressed with (see my first blog on the subject).
A year on, the scooter hasn’t changed significantly, but the price tag certainly has. Last year they were retailing at over £7,000; now the price is £5,600 OTR. With petrol 15% higher in price and rising I needed to know if it would cope with my commute; so I asked to borrow it for the evening and ride home. They agreed; so on Thursday 2008-06-12 I was to pick up a fully charged scooter.
The economics, surprisingly, still don’t entirely add up, it has to be said. There is no doubt that now the Vectrix would save me money on my commute. If I was to sell my Pan European and go electric only then it would save a significant amount of money. However, that’s not practical – for example I’m riding the National Road Rally in a couple of weeks and that requires 870 km without stopping long enough for a recharge. Limiting the range to 110 km (at best) would not work. So the comparison has to compare the full cost of the Vectrix with the additional cost of riding the Honda to work.
First shock is the lifespan of the Vectrix battery. They are predicting it to go 10 years, or 80,000 km, or 1700 charging cycles. Given that I ride 25,000 km per year, that battery would last little more than 3 years. So the economics have to work on the bike being scrapped after 3 years (at least I don’t have to factor re-sale value into the equation). That means £146 per month in depreciation. Then the cost of borrow that extra money over three years works out at another £25 per month (that’s an optimistic number too). However, that depreciation might be overstated as the battery is supposed to be replaceable at a fraction of the cost of a new bike, so it might be possible to reduce that figure. Again, the cost of tyres is a deciding factor here – it’s by far the highest item on the running costs. I’m assuming maintenance can be mostly done by me, and allowed £50 per year, but these small wheels are going to go through around 3 rear tyres and probably one or more fronts per year. Apparently it’s quite heavy on rear brake pads too. That comes to another £40 per month, fitted. With another assumption on additional insurance costs, that brings the total monthly running to around £60. Adding up the running and financing costs, I reckon the scooter would cost £232 per month if it was used purely for commuting.
Comparing this to the cost of the Pan European, as I said, I have to remove costs that would be incurred if it sat in the garage all year. This includes tax, insurance most of the depreciation and one service per year. Pans keep their value quite well, but they also cover very high distances before they are fit for scrap. So I’ve allowed £40 per month for depreciation, and nothing for the cost of finance. The main costs are servicing, tyres and petrol, which come to around £200 per month. Two thirds of this is petrol, so it’s quite sensitive to rising petrol costs. If I assume a petrol cost of £2/litre then the number rises by £100 per month.
So the bottom line is:
  • Vectrix cost per month £232
  • Pan Euro cost per month £240
  • Total saving per month - £8.
Hardly a convincing case, but I suppose if I could reduce that depreciation number it might make sense.

So I turned up at the Vectrix display on Thursday with my lid and leathers expecting to be given a key. A different salesman was on duty this time, and she was a little less optimistic than the chap I saw on Wednesday. She said they’d looked up my address and thought I’d struggle with the range. In fact they were pretty sure that I wouldn’t make the 55 km home if I went on the motorway. That range 110 km is only available if you use urban roads and keep the speed down to 50 km/h or below for most of your journey. Unfortunately that would leave me with at least a 90 minute commute – something I could have lived with for one evening, but not as a daily grind. They spoke about the new generation of battery that would be out in a year or two that might extend the range; and about the concept sportsbike they’ve got in pre-production already – that does 200 km/h with the same range as the scooter. But currently they have nothing to offer that would do my 55 km commute on the motorways and fast A-roads to Canary Wharf. Luckily the Pan European is still in fine fettle and should last at least another 100,000 km (4 years commuting) before I have to replace it. Perhaps the electric will have become practical by then. Who knows where the price of petrol, or indeed electricity will be by then.

Vectrix Electric Scooter

This summer I took a Vectrix electric scooter for a test ride; and I have to say that I was very impressed. With a top speed of 100 km/h and a range of 110 km, this could easily be the first truly usable electric vehicle since the milk float. The acceleration was extremely good; the feel and handling were excellent. With all the weight low down, but with much less weight than the older generation of electric vehicles, it makes for a really useful little machine. I was very impressed with the sales team too. They were both bikers, so they new what they were talking about and understood their customer. They were quite happy to bring a machine with a fully charged battery to my home, follow me on a test ride to work and recover me if the range of the vehicle wasn’t up to it. That may seem rather odd, since my journey to work is only 55 km – half the maximum range of the Vectrix - but apparently the maximum range is not available at the maximum speed. My journey to work looks like this: 5 km town driving (max speed 50); 35 km motorway (max speed 120); 15 km dual carriageway (max speed 80). That middle section of 35 km at what would mostly be flat out for the bike could prove a big drain on the battery and would need to be assessed. In the end I decided not to buy one. Below is my assessment of the pros and cons of this particular vehicle, but my main concern was that the top speed just isn’t high enough. It’s not the time – it would add about 3.6 minutes (or 9%) to my minimum journey time – but the actual usability on a motorway. I watched how I ride on motorways, and came to the conclusion that I do use that top 20 km/h most of the time. Given that more than 60% of my journey is motorway, I just wasn’t happy with having no acceleration above 100 km/h.

Advantages of the Vectrix (over my Honda ST1100):
  • Cheap to run – would cost about £1 a week.
  • Cheap to service – apparently has only 7 moving parts (brakes and bearings)
  • Zero cost to tax

Disadvantages

  • Unknown battery life. Ten years is claimed, but warranty only covers two or three
  • Unknown resale value – Have to assume that it depreciates fully over the warranty period.
  • Lack of top speed for motorway work
  • Unknown insurance costs – Vectrix recommended a broker who quoted a crazy price
  • Unknown range when the battery gets old. I’d be a bit stuck if the range drops off after a year of use and I can’t get to work.

It’s very difficult to get an accurate picture of the true cost of ownership of the Vectrix. With fuel costs at £50 per year instead of £1500 you’d think it would make sense. One model I built, the whole thing hinged on the tyre life, believe it or not. But any realistic model of cost for any vehicle is based on the depreciation. Buying a brand new scooter for £7000 with an unpredictable resale value, compared with a middle-aged big bike with a strong second-hand market just leaves too many unknowns. So it was with some reluctance that I gave up my hope of going electric for my commuting. But give up I have until there’s a bit more top end, and a bit more history on which to base depreciation estimates.
