April 16, 201313 yr Hi there. I would like to introduce my recent work on an electric bike trip simulator. I think that this tool should prove useful to help people to understand how fast and how far they can ride with their electric bike. It is especially usefull for hilly areas as it includes the elevation profile of a trip. I hope that you will like it. Also I know that the trip editing is not very easy and there is a bug if you click on the reload button of Firefox (I don't know why !). Also, you can use the Reinit trip button top start a new trip or simple choose Chrome
April 16, 201313 yr An excellent piece of work. I tried it with my commute and its prediction was the same as my actual experience.
April 16, 201313 yr very good indeed. [ATTACH]5467.vB[/ATTACH] Dont like the Bank Brow bit, see pic, going down is 40mph fun though Edited April 16, 201313 yr by Ettica
April 16, 201313 yr That is pure magic and whats more, even I can understand how to use it Merci Beaucoup...... Lynda
April 16, 201313 yr Just noticed a couple of glitches. I used it again with a similar journey, and the battery % used shows 460% instead of 46%, plus it says very high risk of battery failure for a 20aH battery that only used 9aH.
April 16, 201313 yr Author Thanks for all the positive comments Just noticed a couple of glitches. I used it again with a similar journey, and the battery % used shows 460% instead of 46%, plus it says very high risk of battery failure for a 20aH battery that only used 9aH. Maybe you input the letter "o" instead of the number 0, and the simulator interpretes the number 2o as 2 ? Edited April 16, 201313 yr by evelorution
April 16, 201313 yr I tried it again from start and got the same. Maybe it knows something about my battery that I don't! I've got a spare battery. i''ll put that in my bike and try again. No, it's still the same.
April 16, 201313 yr very good indeed. [ATTACH=CONFIG]5467[/ATTACH] Dont like the Bank Brow bit, see pic, going down is 40mph fun though Here's a short journey I do in the car Wow I wish I had hills as tame as that
April 16, 201313 yr Great bit of software - If it can just take Sustrans Cycle Routes into consideration, it'll be superb.
April 16, 201313 yr I put in an expected regular 8km journey with a steep section and it predicts high risk of flattening both a hub motor with 20Ah battery and a traditional European (presumably crank) drive pedelec with 15Ah battery over that distance. Actually it reckons I'll use 150% of my available battery power in under 5 miles going at a mere 18km/hr with a very high risk of motor failure. Hmmm ! Either something ain't right with the parameter I put in or according to this I'm not going to get an eBike to get me more than about 3 miles with the local hill to the only spot I'd ride to regularly, even buying one of the biggest batteries you can get hold of and travelling at a maximum speed of 18km/hr Edited April 16, 201313 yr by 103Alex1
April 16, 201313 yr I'm sure you aren't making the same mistake I made, but just in case....in the battery section it asks for 'age' and having one of my frequent brain f*rts I entered 67, being my age. I suffered battery failure predictions for a while until the f*rt cleared and I realised it was the age of the battery that was required. I'm embarrassed to have to make this admission but just in case it helps resolve anybody else's problem..... JimB
April 16, 201313 yr LOL. You've hit the nail on the head - I've been doing EXACTLY the same thing ! :o But it doesn't make any difference - 150% of battery consumed on the trip home (which is the bit I need it). So if this turns out to be right (and I hope it isn't), there will be one very expensive eBike getting stripped apart, the bits flogged off for spares and proceeds used to pay for a one way ticket somewhere hot and flat for the Summer !

April 16, 201313 yr It might be useful if you posted the exact route you were planning along with the parameters you input so they could be cross checked, in case there is an obvious input error. JimB
April 16, 201313 yr Yes, I put in my age. I changed the age to 1 and now everything's OK. It might be worth changing the caption to "battery age". The only thing now is that the average speed looks a bit high. On my hilly route on a bike limited to 25kph with lazy power, it's giving an average speed of 26kph.
April 16, 201313 yr It might be useful if you posted the exact route you were planning along with the parameters you input so they could be cross checked, in case there is an obvious input error. JimB Can't work out how to do that, JimB - I just clicked on the map whilst it plotted a route from that. However, have cleared the previous route and replotted it - now works much better - perhaps something got cached that wouldn't update till I re-entered the route. 35% battery use based on either 0 or 1 year old battery for the + /- 10 mile round trip, average speed 15mph using 'Traditional' rider. That gives about 25 mile range allowing for some battery diversion to powered accessories, which oddly enough is about exactlly what I recently posted I'm expecting from the CST in the very hilly terrain I'll hopefully be able to test it in. In real life, you'd maybe get 50-60 miles in 'rolling hill' conditions without long sections of steep ascent using less power. It really does drive it home that if you want to use the power to get you up what I would term "proper" extended hilly stretches without struggling and at a sensible speed (12-15mph), you will cut your range down significantly. In practice you can't "speed" (hardly, but relatively anyway) on these bikes under high power up hill without it costing a lot of Ah, even if the motors are capable of delivering. Just glad I didn't try to get away with less Ah now - would have been a big mistake ! Interestingly the power use of a standard European Pedelec is about the same - but the assumptions about average speed are a little optimistic with those hills involved (to say the least !). Does that category include crank drives ? If so I may have selected the wrong option from motor type ... What do these mean where crank drives are concerned : Geared Direct Drive With transmission Transverse Flux I am assuming the CST is a geared hub motor, but what about an Impulse crank drive ?

April 16, 201313 yr That is pure magic and whats more, even I can understand how to use it Merci Beaucoup...... Lynda Hi Lynda, How are you getting on these days,health OK and still fighting the crave? Lynda you can PM me if you have something to confess,lets keep it hush hush. (it's not easy Lynda).

When I first did it google chrome used form auto complete and put my year of birth in 1961 lol. I did notice in chrome it didnt work when putting in a town as destination so i had to click on the to and from positions on the map Sent from my GT-N7000 using Tapatalk 2

(it's not easy Lynda). Mountainsport. LOL......Im fit and very well......dont know if you could cope with all my possible confessions ROFLOL But vaping still going strong.......how are you ? Im parked up on a wet and windy Kendal drive at the moment Lynda
April 17, 201313 yr Hi there. I would like to introduce my recent work on an electric bike trip simulator. Great job. Plugging in my favourite and routine runs around here, it predicts almost exactly the power I use, so I would be inclined to rely on this for new runs. Thanks for this - a very useful tool.
April 17, 201313 yr Is it possible to get this to work with the Open Cycle Map? That would include the Sustrans National Routes in the uk.
