Considering Dillenger kit but fork may be a show stopper

I am interested in converting a 2010 Specialized Tricross Comp to an ebike. I have a custom steel sport touring bike that is my daily ride and the Specialized is going unused. I would convert it mainly out of curiosity about ebikes. I am 69 and retired and would use it entirely for recreational rides in the city and on nearby trails. I was looking for options that would be easy to install and would allow me to continue using my 105 shifters and existing cantilever brakes. The Dillenger Street Legal kit caught my attention but I saw some posts here that indicated that the forks should be steel. My bike has an aluminum frame with carbon forks. Is that a showstopper? If so, what about a rear wheel drive like Bionx? Do they work with existing derailleurs?

Yes, I think carbon forks with a motor is taking on too much risk of breakage, even if it was a dinky motor. So put on a steel fork. Get to learn about headsets and all that.

I'm 63 and have played with installing a Luna Mid drive. I owned a shop for many years.

Your carbon fork is a no--no---do not put a front wheel motor on it.

You will love a mid drive and it should fit fine on your bike. I would recommend a BBSO2 not the BBS HD.

I would recommend getting at least a 48 or even a 52 aluminum chainring to go with it also. (The bafang steel chainrings are really ugly). I am fonder of bikes with disc brakes to convert. Riding now you are in the 10-17 mph all the time. With the ebike you will probably be 17-25 mph all the time... It may not seem like much but it puts a lot more load on the ability to stop.

Warning---you will become a little boy all over again.

I went with a dolphin battery but I would go with a Bag battery next time (mine is too heavy to be held on with just two waterbottle screws). The bag straps will degrade the paint on your frame but it could also go on a rack in the rear. I just use mine for a little boost and got the 13amp hour $500 battery. I would go with a smaller battery to start-I never use a complete charge and would like the lighter weight. I can keep up with the fastest riders in town on the steepest hill---I have beaten the best strava time up a local climb---I mounted mine on a 26" mountain bike.

Luna was excellent to deal with---they know their stuff. There is a lot of info on the Luna blog that is linked to Luna.

Make sure the battery and the motor have the same connectors---grrrr...

Have fun.

I was out in the DC area a while back with a folding bike---lots of great paved bike trails to ride.----I even went on the island and visited the Teddy Roosevelt memorial. Alexandria down to Mt Vernon and up to the monuments was great.

Dillinger makes mid drive options https://dillengerelectricbikes.com/e...mid-drive.html
Pick a price point and power range.

Thanks. I checked them out and they have a guy named Chad who has helped a lot of people sort out what is possible with their bikes. I may ride over and see him.

It does seem like a center drive is the way to go. Luna has a sale on the BBS02 with battery for $750 which seems good. e-Rad's 350 watt motor sounds a bit more advanced but I'm not sure the extra expense is worth it to me when I am just messing around out of curiosity.

I wish I could believe this $200 Eazy Bike Indiegogo project that Facebook is pestering me with ads about was a real answer but I am way over skeptical.

The Eazy bike is a friction drive - I like them, but they are (1) noisy and (2) suited for intermittent use not constant power-on riding. They work best for someone with a really light weight bike who wants to blip a bit of push now and then. The high pitched noise from constant use will have dogs running after you, lolz.

If you want to check out more versions go read about Add-e or Go-e on Kickstarter.

I've purchased from Dillenger (front hub kits (2)) and from Luna (Bafang BBS02 kits (3)). They have all been reliable and no service problems from either.

With the mid-drive, you lose your front shifter.

With the hub kits, I would probably recommend them on steel forks but I do have it installed on an alum suspension fork but with an added torque arm. I only have one torque arm on the fork which is enough for a 350w geared hub. With a carbon fork, I would get 2 torque arms if you are going that route. For me 350w is as much as I want to put on a front wheel.

That said, I would probably choose between a rear 1000w geared hub or a 750w mid-drive.
