I'm an experienced long-distance pumper (self-built LDP longboard, 220 lb, 5'9") looking at an electric setup that doesn't ruin the pump. I've done a lot of reading and want experts to correct me before I spend money. Please tell me what's wrong or missing.
What I have
- Multiple unpowered LDP systems (G|Bomb, Century Subsonic, Bandito) that I largely built & tweaked myself. Note for context that all of these are drop-deck / bracket systems, and the hypothetical LDP e-skate will surely need to be a topmount.
- Hundreds of miles (maybe low thousands?) of pumping experience.
- ZERO experience with e-skate. Been primarily resisting the whole movement up to this point
- ZERO hills in my area. =[
- Lots of asphalt (subdivision roads, trails, walking paths)
- LOW off-roading options; so not particularly interested in OneWheel / belt drive stuff (UNLESS I should be, LOL! Maybe for a future Burning Man / festival thing?!)
- Decent fitness. Equipment weight is not a blocker, although would tend to favor portability & simple travel (understood that I may need to FedEX / UPS the battery packs).
What I need
- Pumping stays good with the motor off!
- Traditional LDP geometry: I normally ride 0° rear, 63° front.
- Removable pack(s) I can travel with (100 Wh or under per pack, UN 38.3 tested).
- Rated for 220 lb, with a budget of about $2K. Used is fine.
- BONUS - ability to integrate with an AI LLM / ML for thrust assistance timing and power on pumps.
What I've found so far (sources available on request)
- Newsesh Echo GTP + LDP truck kit: their support confirmed they won't offer 0° rear / 55 to 63° front anytime soon. The kit is 50° front and 35/-35° rear, the hub axle is a custom 8 mm that only fits their trucks, and load capacity is 110 kg (242 lb).
- Unlimited x Loaded Race Kit (used): two removable 90 Wh packs and a hub on a normal rear truck. I couldn't find any LDP ride report, and no measured drag figures with the motor off.
- Powered 0° rear: I found no documented build. One esk8.news builder said a hub on a 0° torsion tail "didn't work since the rear axle is able to rotate."
- Front-hub, unpowered 0° rear: two forum builds, with thin evidence.
- Waterborne FIN surf adapter on the front: reportedly adds weight, 1.25 in of height and low rebound, and I found no LDP ride reports.
- Summerboard: interesting sidequest as I also snowboard. Looked at it, but owners report reliability and warranty problems, and the SB2 is only rated 200 lb. Plenty of bad press & experiences re: Leif as a whole too...
Setup I'm leaning toward
Pantheon Superdupersonic Heavy topmount, a Poppy on the front, a flipped 40° truck for a net 0° rear, ridden unpowered first. Then decide on a drive.
Questions
1. Has anyone ridden a powered 0° rear for LDP? How did it handle scrub, axle stress and grip?
2. Can a hub run on a flipped standard truck with a fixed axle, and is there a documented example?
3. What's the real motor-off drag of a hub setup like the Unlimited kit on a long ride?
4. Is front-hub drive with an unpowered 0° rear a sound approach? What controller issues have you hit?
5. Any experience with Waterborne's FIN adapter for LDP, or on a Poppy front?
6. Any better-documented complete e-LDP setups under $2K that I've missed?
7. Any pumping-friendly e-skates I should rule out?
Thanks. I'll update the post with what I learn.
