Well finally picked it up today from the Edinburgh Electric cycles in Edinburgh. First impressions are fantastic, and it pelted down with rain tonight when i was out for an hour, i can safely say that water has no effect on the bike. My only complaint is the tyres they are slicks and i nearly came off on a road which had dead leaves on it, they just feel skitterish, maybe i will get used to them. Going out tomorrow and will give a full review on the bike but it does seem impressive, no squeaks or rattles pretty much silent.

Do not know why i bothered to spend so much money on a bike that i wanted to hide was electric. I was out with my 8 year old daughter tonight and all i could hear was SLOW DOWN YOUR CHEATING :) This went on all night so there was no doubt it was an electric bike with her in tow :rolleyes:

I'll be interested on what you think of theTrek+ as I had a shot on one of them when I was through in Edinburgh a few weeks ago. The hill climbing ability seemed really good and everything seemed so quiet.
I was dithering at the time (and still dither) - let us know the pros & cons when you've had a good run with it
Cheers
Rab

Can anyone advise how many recharges can be expected with the Trek batteries, please?

The Bionx batteries on Trek bikes should when properly maintained, last roughly 800 charge cycles before the cells need to be replaced.

One thing to consider the cost of a re-celled or replacement Bionx battery costs more than quite few complete electric bikes:eek:

Hi guys sorry i have not been on much lately and updated on the progress of the Trek. I have been using it daily for my 40 mile commute to work, 20 miles each way. I have been using the bike 7 days a week bar 3 days when we had 3 foot of snow, just stayed at home :)

After 3500 miles the Trek is still riding like a new bike, the motor is if anything pulling stronger. I use this bike in all weathers and nothing bothers it, rain snow hail it just keeps going.

But down to the details, i am now even more convinced that this bike is for people who are reasonably fit who want to lose weight rather than an all out electric bike. The trek has 4 levels of assist the first 2 are a complete waste of time if you are looking for electrical assist. In fact level one is probably worse than riding a normal bike as it does not compensate for the extra weight. Level 2 i would say is enough to compensate for the extra weight, so good for getting fit. Now if you use level two you could achieve at least 30 miles i reckon before the battery is dead. But as i say on level 2 you really do need to work at it, not excessively but you do know you are cycling up a hill. Now slot into level 3 and now we are talking, the weight disappears and the bike feels ultra light at speed and you can push up hills with very little effort. Do not get me wrong on very steep long hills you do still need to work at it, but not too much effort. On lever 3 i reckon you could easily do between 14-20 miles of mixed terrain. Now slot it in level 4 and you really are doing no work regardless of the hill, as far as i am concerned you might as well be getting the bus :)

But you do pay the price for level 4, i reckon you are down to single figures on battery range possibly pushing 10'ish miles. But in reality you use a mixture of 2,3 and 4 and with a 17 stone rider on a hilly terrain you can get about 17 miles out of it.

Nothing on the bike has given me any trouble so i can only report back that the bike has been 100% reliable. I had a small issue with the front light that the wires would be stretched on full lock so i extended them, no big deal but then again its not a cheap bike. The seat mount snapped but that was my fault, it was creaking when i left work and i never bothered to tighten the clamp and it snapped. No big deal as i was looking for a more comfy saddle anyway, bought a selle royal gel saddle which is fantastic. The frame has picked a few dents up but i am rough on my bikes and alloy frames are soft so not a fault of the bikes. But the bike is still absolutely silent, i mean silent no one could ever tell it was an electric bike unless you told them. I have vaude panniers on mine which hide the battery so absolutely no indication its electric. The silence of the bike still impresses me to this day, i test rode other bike and the noise put me off them.

As for battery life Trek claim 500 charges but i cannot comment on this. But i charge the battery 2 time a day since September and if anything its even stronger now so no idea but 500 sound realistic.

Overall i would say, fantastic fitness commuter bike, but pure electric bike NO unless you do less than 15 miles then yes you could use assist 4 all the time. I have lost 2 stone since using it so i am 100% over the moon about the bike.

In summary it is one very high quality electric bike designed as a mid way machine between a pure electric bike and normal bike. Will post some pictures tomorrow as i need to wash it as the grit is causing me hassle with the gears.

Many thanks, overlander, for the detailed reply.

My local dealer has an FX+ in for me to try. Based on your experience, it sounds as though it will be suitable: I'm nearly 11 stone, and want a bike to commute about half your distance - with one significant hill (over 5% for half a mile, rising to a max of 12.5%). I'm interested in this one in particular because, having followed this forum for a while, I feel that a locally supported machine is desirable. It also has the attraction, for me, of enabling me to continue cycling as near normally as possible.

Once again, thanks - very helpful.

Thanks, Aldby. The cost of batteries is a concern, but if I get anything approaching the 500 charge cycles suggested by overlander I can live with that.

You are right, the Trek is possibly not good valuefor money, but I think I'll appreciate the quality of components and local support.

Time for a test ride.:)

I would say that the Trek is value for money, the price of quality electric bikes does seem to be near the or above the 2K mark. There is no way you could buy all the bits separate for anywhere near the cost. But i would say if you are buying in at the top end be 100% certain an electric bike is for you. There are many a dark cold morning when the temptation is to leave the bike, if i did not need to lose weight i would have taken the car.

PS forgot to add a replacement battery is £450.

Thanks for the review - very useful as you reviewed at it purely as a commuter (who lost a good bit of weight admittedly) - without going over the top about anything, and just calling it as you saw it. I think I may make a visit to Edinburgh Electric Cycles as they have a few in stock

Thanks again

It won't be available for delivery until March/April but there is a BionX-powered Kalkhoff on the way this year. It uses the 250W High Torque version of the motor with the latest console, all installed on a very good bicycle platform that won a major consumer test even before being given the electric treatment.

The Kalkhoff does look a good bike but why so little frame sizes? One of the main advantages of the trek is the frame range for each bike ensuring a good fit rather than a compromise. Personally i need a 63.5 cm frame, so for me the Kalkhoff is just a toy. But i should add after thinking about it, Trek is massive i guess they can afford to make frames in the less popular sizes as they have the clout with the suppliers.

Nice looking bike Tim - like the colouring and the battery moved back into the "triangle" - I would imagine that even with the electrics on it, that's a well balanced bike as the original bike (B27) seems to have been well thought of by reviewers
